How much DNA are in human body cells?
There are about 50 million or 50 trillion in the adult body. But that isn't always true. It may not be true because cells die and form again. And it will be hard to count all the cells. Adult and child cells don't add up because and adult is big but a child is small so the child will have less sells. So 50 million or 50 trillion is the correct estamate in the human body. P.S. NERD SQUAD IS THE BEST!

Human Dna in Diploid -Somatic- Cells has the extended Length of 1.87 meters. Sperm and Egg Cells -Gametes- are Haploid Cells, with one half of The Genetic Complement, so the length is 0.935 meters [repeat - in length - jammed into a Space about three microns across].
if you mean length its roughly 2 meters if you want the chromosomes there are 24 pairs
Red blood cells (otherwise known as erythrocytes). They contain no DNA or organelles. They lose them whilst maturing so as to be able to pack more haemoglobin into the cell and therefore be more efficient oxygen carriers.
The only cells which lack DNA are the mature red bloodcells (erythrocytes). This is because they lack anucleus, which is where the DNA is found in other cells. Red bloodcells also lack mitochondria which themselves have DNA. Thereforethey not only lack nuclei DNA, but mitochondrial DNA as well. Red… blood cells develop in your bonemarrow from special cells called stem cells. These do have anucleus, but as the red blood cell develops the nucleus issqueezed/taken out. This makes more room for the red pigmenthaemoglobin, which is needed to carry the Oxygen in the red cells.Haemoglobin also carry's Glucose needed for energy and also theytake Carbon Dioxide away from the cells to be breathed out throughthe lungs (MORE)
no, not all cells have the same specific DNA but the DNA can all be traced to the one person it came from
Almost every cell has nuclear DNA. The exception is mature red blood cells (erythrocytes), which extrude their nucleus during development. Without a nucleus, they cannot live long; the average life of a red cell is 120 days. In addition, all cells contain mitochondria, and these contain mitoch…ondrial DNA (mtDNA), with 37 genes. (MORE)
Yes, (except for slight random replication mutations that may happen due to exposure to radiation or harsh chemicals or invasion by viruses) apart form the egg and sperm cells which contain only half the DNA.
Blood makes up about 1/12 of body weight. As there are 12-16 grams of haemoglobin per 100g of blood, the weight of blood cells based on body weight is 1%. So yes but its made up of many other things too like tissue and white blood cells.
DNA in the human body is located in the nucleus of each and every cell in the human body.
What are some of the benefits of squeezing so much data into virtually every cell in the body Why did humans not evolve with one central repository of DNA rather than having it replicated throughout?
What are some of the benefits of squeezing so much data into virtually every cell in the body? . A DNA strand contains a complete representation of everything about our physiology. It also contains instructions on how to form our body by repeated divisions of a single cell. Each cell needs to know… when it should, split into two, split into different kinds of cell for tissue differentiation. Cells also need to know when to stop growing because the body or organ is mature, and when it needs to replace tissue lost by injury. All of that is encoded into one molecule. So in other words the benefit of squeezing a lot of data into our cells is that our cell knows what to do and when to do it.. Why did humans not evolve with one central repository of DNA rather than having it replicated throughout the body? . DNA contains instructions on how to make proteins. Each cell uses its own DNA to make proteins which it needs to do its job. Other parts of the DNA tell the body what cells to make, but even this job is done by other cells, which split, differentiate and turn into organs because of the instruction in DNA. That's why it is in every cell, and not in some central place, because every cell was split off from some other cell that also had a full set of DNA.. Assume that the hereditary information carried in genes and DNA is responsible for many differences observed in humans and other living things. How could just four different bases in DNA strands be responsible for the almost endless variety found in nature? . The same way 1's and 0's are responsible for everything that comes out of computers. While the code itself is simple, it codes for very complicated things. The 4 bases of DNA lead to very complicated proteins according to set rules. DNA has four bases, represented by the letters A, T, C and G; the initials are of the chemical names for those bases. They are arranged in groups of three, each group being called a codon. So ATA is one codon, CGT is another. Even with only four letters, you can get many codons and thus very complicated instructions.. \nI'm no expert, but your body grows by producing cells. They DNA code is transmitted to each cell so they all will match. If not, then you would have brown hair on one side of your head and red on another or one arm would be longer than another. That is simplified explanation. (MORE)
The DNA in all of your somatic (body cells) is exactly the same. Only in the egg and sperm is different.
The nucleus of a cell is what gives it its structure. There are 92pieces of DNA in the nucleus of a cell.
It contains the information necesary for your bodies uniqueness. Like the blueprints of a building.
DNA is present in all human cells, except the red blood cells, that is because RBCs do not contain the organelle nucleus or any other DNA containing organelle like mitochondria.
If unraveled and lined up end to end they would be 13020 million miles long
DNA is found in every cell througout the body, with the cells, the genetic information is contained within the nucleus of each cell
If you pack too much DNA into a cell what would happen is this, it takes a lot of nucleotide bases to seta all the instructions an organism needs. the total set of instruction for a human being is over 3 billion nucleotide and would stretch almost 6 feet in length if you lined up all the bases!
DNA is a series of amino acids that are strung together to forma long strand, these form the chromosomes , whichare located in the nucleus of the cell .
In one human cell, there are 2 metres of DNA. Which means that a human has about 200 trillion metres of DNA in their entire body. No... theres 3.6m of DNA per cell
The human genome contains 3,079,860,316 base pairs of DNA, arranged in 23 pairs of chromosomes plus mitochondrial DNA. These form 32,185 distinct genes.
Regardless of age, every single cell in the human body, with the exception of red blod cells, contains DNA
DNA will survive in the environment for less than one million years and slowly degrades into short fragments in solution. Claims for older DNA have been made, most notably a report of the isolation of a viable bacterium from a salt crystal 250-million years old, but these claims are controversial.
Humans have 23 pairs of chromosomes, and just over 3 billion base pairs. Each cell in the human body has about 2m of DNA (if it were stretched out). This means that an average human's DNA would be 2 * 10 11 km long! This length is 500,000 times the distance to the moon (4 * 10 5 km).
Enzymes are used to cut and paste DNA from one source to another. Enzymes called restriction endonucleases are capable of cutting DNA at specific sites called restriction sites. These sites are typically 4 - 6 nucleotides in length and occur several times in the genome of almost all organisms discov…ered.. Enzymes called DNA ligases are capable of pasting (or ligating) two strands to DNA together.. DNA from one organism can be cut at specific locations using restriction enzymes and then pasted into a different source (like a plasmid for example) using DNA ligase. (MORE)
There is no single percent number. At any given moment, depending upon your diet (meats, legumes) and pathogenic interaction (viruses), you may have as little as 0.00003% or as much as 0.02%. That sounds like almost nothing, but is really alot if you consider DNA recombination.
We have a different kind of cell for every part of your body.We have the white cell which kills germs.The red blood cell makes the blood.
Every human has the same DNA but the chemical that make the DNA are just in a different order.
Two places: the DNA that gives instruction for the construction of the person is inside the nucleus and there is also mitochondrial DNA in the outside of the nucleus in the cytoplasm (the fluid filling of the cell).. Mitochondria are cell organelles in the cytoplasm of eukariotic cells that generat…e adenosine triphosphate (ATP) which is used as a source of energy. It is believed that mitochondria were bacteria that were absorbed during the evolution of the eukariotic cell. They produce their own DNA and replicate themselves separate from the DNA of the host cell. This is why mitochondrial DNA is inherited only from the mother. (MORE)
not alot but alot. There are about 69500 single cells in in the DNA, but there is 46 DNA in the typical human body.
A human cell has 46 chromosomes, 23 from each parent. Each chromosome is a separate stretch of DNA. Approximately 150 human cells yield 1 ng of DNA.
All cells have DNA strands in the nucleus, except mature red blood cells which don't have nuclei.
A cell must hold a sufficient number of base pairs in its chromosomes to encode its entire genome. Bacteria may have 10^4 base pairs on the small end, while mammals may have several billion base pairs, plus extra-nuclear DNA inside mitochondria, and other *RNA in the cytoplasm. Under extra-ordinary …circumstances, a cell infected with a DNA virus may hold abundantly more DNA, but only temporarily until it lyses. (MORE)
Deoxyribonucleic acid (DNA) is two strands of Ribonucleic acid (RNA) that have been put together. See http://nobelprize.org/educational_games/medicine/dna/index.html for a more detailed answer.
Well most of the body contains DNA but nobody knows really how but DNA you have in your body.
DNA is packed into chromosomes in the nucleus and humans have 23 pairs of chromosomes in every cell
No - well, sort of. The DNA in every cell is almost the same, but a tiny snippet of each DNA strand codes the specific job the cell does, and that's what makes each cell's DNA slightly different. For example, the code for a skin cell is different from that of a liver cell. The differences in the "…job code" is what makes groups of cells different from one another. (MORE)
G1 - 46 single-chromatid chromosomes = 46 DNA molecules; s - replication takes place, so that at the end of S and in G2 - 46 double-chromatid chromosomes = 92 DNA molecules
You draw the deoxyribose first (labelled S), connect it to a phosphate group (P) then a base connects to the deoxyribose. Between the bases, are hydrogen bonds. Or just draw two spirals and draw different colored bands to represent the 4 base
From 20,000 to 25,000 genes, 3 billion base pairs that would stretch yo about 6 feet if strung in a strait line.
The answer is NO. You can modify a particular part of the DNA by mutation but an entirely different DNA cannot be incorporated into another DNA simply because DNA is present in each nucleated cell of the body and as there are millions and millions of such cells, its not possible to do it. :)
the human genome contains about 3 billion base pairs, they are curled up in a double helix, each turn takes 10 base pairs and is 3,4 nanometers in height that means: (3*10 9 /10)*3,4=1,02*10 9 nanometers = 1,02 m. This may seem unreal but keep in mind that our DNA is very compact because it is …wrapped around a proteÃ¯n skeleton (MORE)
The only two types of cells that do not carry a full strand of DNA are the male sperm cells, and the female egg cells.
DNA is the genetic code for your body. DNA tells what color your hair is going to be or what skin pigment you will have-- how much melanin your skin will produce. It even tells what kind of nose you will have and what your lips will be like. It makes you who you are. Chromosomes, strands of DNA pack…ed together, also tell if you will be Autistic or have some genetic disease. Some diseases are caused by the mutation of DNA, but not all, such as AIDs. (MORE)
Somatic cells are body cells which are important part of the body's multicellularity and function. So they should have same DNA code in order to maintain a balance in the functioning of the body. And except sex cells (gamates) all the cells of human body (i.e. somatic cells) have the same DNA code. …Another reason for this is mitosis. As body cells arise from mitosis, the division is conservative and doesn't involve any process of inducing variation in the cells, hence all the cells originating from it have the same DNA code. (MORE)
DNA is your cells give you your genetic information which is what makes up who you are. you receive it from your parents through genes. they help control how your body performs functions and what you look like.
no because a full grown human has more cells and each cell has DNA so it would have more DNA by extension.
No. The amount of DNA in human sperm cells is half of the amount found in body cells.
I am not certain what it is that you are asking. The two strands of DNA that are a part of the double helix are notthe same; they are complementary. Each purine is matched with apyrimidine (A to T, G to C). Each cell of one individual (with few exceptions) contains the sameDNA, all 46 chromosomes …worth, but different genes are activedepending on what type of cell it is. Your skin does not use thegene that codes for amylase, an enzyme found in saliva, even thoughsomewhere in the nucleus of a skin cell that same gene can befound. Some 90+% or so of human DNA is the same between members of thesame species, but in a single human body--We have two copies ofeach chromosome, two copies of every gene, and it is possible tohave two copies of the same allele. The likelihood of this is notsomething I am prepared to preach about; however, I am certain thatit varies depending on what gene you're looking at (and even whatyou define as a gene...). For instance, to have type A blood, you would have either twocopies of the "A" gene, or "A" and "O." "O" is recessive and is notexpressed in the presence of a different allele. The former is acase in which some of the DNA may be the same, as the cistronproduces the same type of protein. But this is only a possibility.Because there are often several different combinations that codefor a single amino acid, there is more than one way to produce thesame protein. So, even in this instance the DNA may not be "thesame." All this is dependent, of course, on what was intended by thequestion. (MORE)
No. Not all cells have a nucleus, which contains nuclear DNA; but all cells have mitochondria, which have their own DNA, called mitochondrial DNA, or mDNA. In humans, the cells that lack a nucleus and therefore nuclear DNA, are mature red blood cells, but they do have mitochondria and mitochondrial …DNA. (MORE)
As you probably already know, all of the cells in your body started from a single cell.\nThat single cell then divided many, many times to turn into the 50 trillion or so cells that make up you. Almost all of the cells in your body share the same DNA as was found in that first cell*.\nSo if they hav…e exactly the same DNA, why are eyes and lungs so different? The answer lies with what DNA is and how it works.\nYour DNA contains all of the information needed for making you. This information is stored in the over 20,000 human genes found in almost all your cells. (MORE)
