"Human cells vary in size and volume. DNA is fixed in its size. That makes it kind of hard (like impossible) to state a concentration for DNA. Only a range can be given, and that information has little to no practical value and even less meaning." Cell size and volume have nothing to do with… the absolute amount of substance measured in mol, which is what the ill written question probably meant to ask. Each human cell contain a genome of about 6*10e9 bp. One mol of whatever substance is comprised of ~6.022 10e23 molecules. Therefore if you were to degrade the genome to single nucleotides, you would get approx 10e-14 mol of these from any single diploid cells, that is 10 femtomol. In a million cells, you would have in the order of 100nmol. The question might seem inane, but it HAS practical value. If you do have to actually totally digest genomic DNA like I had at some point, and you're given a definition of enzyme activity in unit based on nanomol of DNA, you just sit there and calculate Now for molarity. While molarity wouldn't mean much, also because DNA is not really in solution in a nucleus, it is practically useful to know how much (mass of) DNA there is in a single cell. The molecular mass of an average deoxyribonucleotide is 330 dalton. So one mol of it would weight 330g. Therefore 100nmol in your million cells above would weight 33ug. Which doesn't sound too far off, since DNA extraction yield for a million cells is actually around 8-10ug. Happy? (MORE)
It's probably a fairly small proportion. According to evolutionarybiologist Robert May, President of Britain's Royal Society, "Weshare half our genes with the banana" (2001), but genes only makeup 2% of human DNA - the answer depends on what proportion of theremaining 98% is the same. Humans have 23… pairs of chromosomes andbananas 11 pairs - even if the 11 banana chromosomes were identicalto human ones (they're not) it would still mean that less than halfof human DNA would be found in a banana.

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].
We will not know the answer to this until the genomes of whale species are sequenced. However, given that whales and humans are mammals, they would be expected to share many similarities.
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)
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! (MORE)
no, not all cells have the same specific DNA but the DNA can all be traced to the one person it came from
Humans do not share much DNA with an apple. They share only about40% of the same DNA.
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.
The DNA in all of your somatic (body cells) is exactly the same. Only in the egg and sperm is different.
No matter the context, a yard is exactly one yard long.. No matter the context, a yard is exactly one yard long.
Humans and cats have similar x and y chromosomes and have the sameancestor from the past. Cats and humans share 90 percent ofhomologous genes.
The nucleus of a cell is what gives it its structure. There are 92pieces of DNA in the nucleus of a cell.
Surprisingly, according to the related link below, domestic bovines (or the colloquial "cow") actually share 80% of genes with humans.
If unraveled and lined up end to end they would be 13020 million miles long
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.
Who cares science sucks!!. This would depend on the same person each DNA strand is dedicated to something different such as hair or eye color yet I do not have much experience on the subject and that is just my basic understanding.
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)
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)
The only way a retrovirus can change the DNA in a sperm cell is if it successfully implants its own DNA into the sperm DNA. Studies have been done with the HIV retrovirus to show that the virus can successfully get inside a sperm cell - but it has never been shown that the HIV virus successfully …implants its DNA into the sperm DNA. In order to get to sperm in the first place, a retrovirus has to get past the blood-testes barrier - which protects developing sperm from outside infections. The only way HIV is able to do this is because it infects white blood cells which are able to sneak past those defenses. So, any retrovirus that has a chance of infecting a sperm cell must first be able to get past the blood-testes barrier - which seems to be limited to only retroviruses who are able to bind to white blood cells. Cells have unique binding cites, and only certain viruses are able to attach to certain ones. (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.
the length of a typical DNA molecule is roughly 1.6 mm - Stretched out the length of DNA in a human cell is approximately 3.6 meters
Most any cell of the human blod can be sused. The most commonly used are epiphelial cells of the skin or cheek. One can also use the cells found in the blood (other than red blood cells, which have no DNA in them).
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.
Depending on what you want to know, I have two answers... 1. If you unwound and tied together the strands of DNA in one of your cells, it would stretch up to six feet, but they would only be 50 trillionths of an inch. 2. If you could unwrap the DNA you have in all the cells in your body, you… would be able to reach the moon and back 6,000 times. (MORE)
All cells have DNA strands in the nucleus, except mature red blood cells which don't have nuclei.
It is commonly though to be 98%. However, recent studies have differing views. The BBC has published 95%, and Riken (a Japanese Lab) has published 85%. Please see the related links for the articles.
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)
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
we are all bannas and slugs and apes so they had a three way atsome point
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)
I'm sure it differs with each species but I know human DNA and chimpanzee DNA only differ by 2% if not less
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
I've just come back from Borneo. The rangers at the Sepilock sanctuary have said the DNA is 96.4% the same.
5 million cm long it is also connected to your head and if broke you will die
If stretched out from a single cell, the DNA would be about 2-3m long. The total length of DNA present in one adult human cell is calculated by the multiplication of: (length of 1 base pair)*(number of base pair per cell) = (0.34 Ã 10^-9 m)(6 Ã 10^9) on average.
no because a full grown human has more cells and each cell has DNA so it would have more DNA by extension.
All living creatures on earth share some amount of DNA, including mammals, reptiles, fish, plants, sea sponges, bacteria, and viruses. Humans share much more DNA with mammals than any other creature. And we share more DNA with lizards than we do fish. This is because mammals split off from the mamma…l-lizard common ancestor long after the fish-amphibian common ancestor. Humans share as much as 50% of genes with plants, so our relatedness to nuts is around this figure. It is interesting to note that researchers have found various genes associated with human ailments in different creatures. For instance, the gene connected to deafness has been found in some plants.

To my knowledge, the crow genome has not been sufficiently analyzed for a definite answer. The process of complete genome analysis is time consuming and expensive, so scientists have been selecting organisms that are highly used in research for genome analysis. That said, the genome of the chicke…n has been mostly completed. Given that chickens aren't that much closer to or further from humans than crows, the DNA similarity between humans and chickens is at least in the same ballpark as humans and crows. The chicken genome is about 1/3 the size of the human genome (1.2Gb instead of 3.4 Gb) but this is not due to much to birds having fewer genes as having mostly the same genes more compactly arranged in chromosomes. My own experience (I have a little experience with chicken genetics) has been that chicken genes tend to be about 75-85% identical with human genes. (MORE)
Humans share very little with a potato. Chromosomes are acollection of DNA woven around protein. A chromosome may contain asmany as 100,000 to billions of nucleotides in one chain. Chimpanzeeand humans share a very SIMILAR DNA pattern, where as a potato anda human being don't. So although they both …have 48 chromosomes,their DNA STUCTURE is vastly different. (MORE)
I don't completely understand what you mean by "pieces". Humans have 23 pairs of chromosomes. That means they have 46 "pieces". 23 come from each parent. DNA is concentrated into little rods called chromosomes. There are two "pieces" on each chromosome.
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)
There is as much DNA in white blood cells as any other cell. There is none in red blood cells.
