Which blood cell has DNA?

All groups of white blood cells have DNA. When a blood sample is procured for the isolation of DNA, the white blood cells are the target cells since they have nuclei containing DNA. Red blood cells on the other hand, contain neither nuclei nor DNA


How much DNA is in white blood cells?

There is as much DNA in white blood cells as any other cell. There is none in red blood cells.


What is the source of DNA in blood?

DNA in blood comes from white blood cells, which contain the person's genetic information. When blood is collected for testing or analysis, the DNA can be extracted from these cells to study and identify specific genetic markers or sequences.


Why do you extract DNA from white blood cells rather than from red blood cells?

The only DNA in blood would be the DNA contained in white blood cells as red blood cells have no nucleus and therefore no DNA.Read more: http://wiki.answers.com/How_do_you_extract_DNA_from_blood#ixzz1TMsImbnt


What if your skin cells have the exact same DNA as your blood cells?

This would be normal. All body cells have the same DNA, including blood cells, at least at some point during their life cycles. Mature red blood cells do not contain DNA because they do not have cell nuclei. But when red blood cells are first formed, they do have a nucleus with DNA identical to the rest of the body cells.


Does mammalian blood contain any DNA?

White blood cells carry genetic information. In mammals mature red blood cells do not have DNA because they do not have nuclei. They expel them during the maturation process. However, in birds and reptiles they have nucleated red blood cells. Thus reptile and bird red blood cells do contain DNA.


Why do frog blood cells contain DNA while human blood cells don't?

Not true. They both do. DNA is contained in all living cells.


Is identification based on blood typing more accurate than DNA testing?

No. Blood-typing is an older technology and far from conclusive since many people share the same blood types. DNA is at least as accurate as a fingerprint while blood typing only helps to narrow things down. Blood typing is more exclusionary in that if you have a different blood type, that proves innocence, but having the same does not prove guilt.


Does red blood cells have DNA?

They do. Mammals are the only vertebrates without a nucleus in their erythrocytes.


What of your body's cells contain DNA?

red blood cells


Why do scientists use the white blood cell when extracting DNA in gentic screening?

White blood cells (unlike red blood cells) have nuclei containing genetic material. Since DNA is present within the white blood cells and since blood is easy to obtain from the body, scientists use white blood cells to extract DNA


Where can you not get DNA from?

dna isn't found in red blood cells
