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.

In eucaryotes, DNA is only found in the nucleus of most cells, mitochondria and chloroplasts. In procaryotes, DNA is found in the cytoplasm in an area known as the nucleoid and in small, circular pieces of DNA called plasmids. Some animal viruses, plant viruses, and bacteriophages also contain DNA.
\n. \n99.9% is exactly the same. .1% gives each individual their own personal fingerprint. Meaning, only .1% codes for proteins that express our differences.
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.
The DNA is found on the chromosomes, which is found in the Nucleus of the cell.
if you mean length its roughly 2 meters if you want the chromosomes there are 24 pairs
The DNA molecule consists of two polynucleotide chains in the form of a double helix, containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine.

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)
Chromosomes are microscpic thread like strands composed of DNA. (DNA - Deoxyribonucleic acid) Over all, DNA contorls the production of proteins inside a cell. The proteins are used to control all chemical process within the cell.
Francis Crick and James Watson are primarily credited, although Maurice Wilkins also helped them and received the Nobel Prize for it. Also, Rosalind Franklin took a photo of DNA, which was stolen and given to Watson and Crick without her permission. They then used it to discover the double helix sh…ape of DNA. She got very little credit having been ignored and then dying of cancer just before the others received the Nobel Prize, as you cannot get this if you are dead. So Francis, James,and Rosalind got credit for finding DNA!!!! (MORE)
DNA is found in the nucleus of a cell. In addition, trace amount of DNA also found in Mitochondria and chloroplast.
Humans do not share much DNA with an apple. They share only about40% of the same DNA.
DNA is also known as deoxyribonucleic acid. It is found in thecell's nucleus as nuclear DNA. A genome is a set of DNA.
DNA is a genetic material formed of protein and is predominantly found in nucleus of eukaryotes. It is also found in other cellular organilis like mitochondria and chloroplasts. But in prokaryotes (eg. bacteria) the DNA is locates freely in the cytosol.
DNA is found inside of the nucleus in a cell.but in our body where is it found it is found in the white blood cells. :D
Some people ask can you mix human and animal dna. My answer is yes you could. As long a you took thprocedure slowly and combined the dna one step and small amount at a time it is possible to mix the dna. My question is would the human gain attributes from the animals dna such as enhanced hearing, si…ght, sense of smell, a tail, and ears or something like that. If scientists can find a way to successfully combine human and animal dna without casualty I would volunteer for it. (MORE)
Humans and cats have similar x and y chromosomes and have the sameancestor from the past. Cats and humans share 90 percent ofhomologous genes.
Surprisingly, according to the related link below, domestic bovines (or the colloquial "cow") actually share 80% of genes with humans.
No one for sure knows exactly, but one recent (December 2008) total is 3,093,120,360 base pairs in the entire human genome (chromosomes 1 to 22, X, and Y).
Chromosomes vary in size, but the DNA would generally be a few cm (inches). The total length of one copy of all chromosomes is about 1 meter (a little over 3 feet). Since you have one copy from each parent, the total is about 2 meters per cell.
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
A German Chemist, Friedrich Miescher, discovered DNA in 1869, only four years after Mendel's work was published. Miescher extracted a white substance from the nuclei of human cells and fish sperm. he called this substance "nuclein" because it seemed to be specifically associated with the nucleus.
A human ;) But the human DNA is developed from the zygote, so when the sperm fertilizes the egg in the womb.
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).
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.
the strand is found to contain 30 % adenine so we going to have 27 percent thymine and 20% cytosine
All the DNA is chemically the same. It is the sequence pattern (the way A, T, G, C organized) would differ from one species to another. The DNA of bacteria from one species to other will differ tremendously if they are distantly related.
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
Chemically DNA from any species is the same. But the things is the sequence of DNA such as AATTTCGAATG for example will not be the same. In fact, the sequence can not be the same from person to person. That is the unique nature of DNA.
I'm sure it differs with each species but I know human DNA and chimpanzee DNA only differ by 2% if not less
The DNA of bacteria differs from human in terms of shape and structure. DNA of bacteria is double stranded but circuler whereas human DNA is spiral.
DNA is exactly the same in every species it is found in. It always has a sugar-phosphate backbone and the same four bases - A, T, G and C. The only thing that changes is the number of genes found in the DNA (and the sequence of the bases).
I've just come back from Borneo. The rangers at the Sepilock sanctuary have said the DNA is 96.4% the same.
No - only a small part of human DNA is coding DNA. About 3% of DNA is genes. These are the sequences that code for a functional unit (like protein).
Define "close." DNA is, despite the popular image, not really much at all like a blueprint for a complete organism in the sense of having some kind of "image" embedded in it. It's rather a description of how to make the tools, how to cut and treat the wood, how to join two pieces of wood together…, and when to stop doing that and start doing something else (in other words, it's not "make the living room 20' square," it's "put boards every 16" until something gets in your way"). (The science word for this is emergent : it's not always clear what the result will be until you actually follow the rules.) As that analogy suggests, the tools, treatment of the wood, and so forth are going to be pretty similar for both a split-level ranch and a Victorian mansion, even though the two may look wildly different when completed. Similarly, the basic functions of cells are awfully similar in a dog and in a human... or in a tree, for that matter; they have to know how to replicate their DNA, how to lyse glucose and extract energy from the process, how to build enzymes, and so on. This part of the instructions is going to be more or less identical with minor variations between any two Earthly organisms (life on other planets may, or may not, be rather more different... we don't have any examples yet, so we don't know).

Where are sex chromosomes found in humans. Are the same DNA genes found in all the cells of a person?
For women, sex cells, also called eggs, are located in their 2 ovaries. For men, sex cells, also called sperm, are located in the genital area. Every cell in your body has it's own unique DNA code, and this code tells all your cells what to do and how to reproduce to make identical daughter cells (i…n the case of mitosis, or asexual cell reproduction). The DNA code is the exact same throughout your entire body, however your cells also contain certain traits called alleles. Alleles are what determine things like your hair, eye, and skin color, and whether or not you have certain physical traits, such as dimples, a widow's peak, freckles, and many others. When a female's egg is fertilized by a male's sperm, the offspring that forms gets one allele from each parent. This is why kids never look exactly like their parents, but may share traits from both of them. For example, you may be heterozygous for brown eye color, meaning that you inherited one brown allele from one parent, and, one blue (or any eye color other than brown) allele from your other parent. Since brown eyes dominate over blue eyes, your offspring will have brown eyes. (MORE)
DNA was found in 1741, they were using a telescope and then Albert Einstine was the first one who told Galileo to use the telescope to see the stars and observe the amazing and incredible awesome answer done by me sorry if it's all wrong.....i want the same answer to for my science project LOL
Most likely no. DNA is far too complex to "mix." If you wanted a mutated monkey tiger baby for a pet, the you might want to go ask this question somewhere else. Mixing DNA isn't as simple as dropping a toenail from a human and fur from a tiger into a mixing pot and then feeding it to a baby monkey. …=_=" DNA takes maybe a yard long strand to just code for maybe your eye color, if not more.

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.

I'm not sure if the term intestine is technically appropriate for the digestive tract of an insect, but whatever the proper label is for insects, if an insect had just eaten some human tissue, then it could possibly contain some human DNA. However, the human DNA would most likely be heavily denature…d and degraded by digestion. The process of digestion is highly destructive for nucleic acids and it is likely that the DNA would be reduced to individual nucleotides and oligonucleotides rather than long stretches of human chromosome.

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)
A human chromosome contains between 454 (Y) and 4,220 (1) genes, totalling between 46,944,323 (21) and 247,199,719 base pairs, for a total of 32,185 genes and 3,079,843,747 base pairs. In other organisms, the number of nucleotides in a chromosome can vary from 100,000 to over 3,750,000,000.
The human DNA is associated with a protein (histone) so it'swrapped around it, then folded and twisted so it's compact, andforms the chromosome shape. The plasmid is very small and containsDNA for survival (e.g. antibiotic resistance gene) and is notassociated with a protein and found in bacteria.
DNA, or deoxyribonucleic acid, is usually found in the nucleus of a cell. It makes up a spaghetti-like substance called chromatin, which coils into X-ish-shaped chromosomes during mitosis. Additionally, small amounts of DNA can be found in the mitochondria of a cell, called mitochondrial DNA.
DNA is the genetic material of all livingthings on the Planet and it holds the instructions for making allthe proteins in our bodies. DNA is found inside a special area ofthe cell called the nucleus.
Human DNA contains about 30% each of adenine and thymine, and about20% each of guanine and cytosine.
