∙ 15y agoThe only DNA in blood would be the DNA contained in white blood cells as red blood cells have no nucleus and therefore no DNA. Extracting DNA from blood is very easy in a laboratory nowadays. The sample of blood is treated with detergants to break open the cell membrane spilling the contents. Enzymes are now used to break down all the protein, RNA, sugars and fats in the solution. Ethanol (alcohol) is often used in the final stages of DNA extraction as under the right conditions as DNA will dissolve into it but other componants of the cell will not allowing the separation of DNA to be used for analysis

∙ 9y agoMatured red blood cells don't have DNA in them, because these cells have no nucleus. However, blood itself contains other types of cells that do contain DNA, and these cells can be used.

How valuable are red blood cells in DNA typing?
absolutley nothing red blood cells contain no DNA
Does red blood cells have DNA?
They do. Mammals are the only vertebrates without a nucleus in their erythrocytes.
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
What cells do not contain DNA?
The only cells which lack DNA are the mature <b>red blood cells</b> (erythrocytes). This is because they lack a nucleus, which is where the DNA is found in other cells. Red blood cells also lack mitochondria which themselves have DNA. Therefore they not only lack nuclei DNA, but mitochondrial DNA as well. <br /><br /> Red blood cells develop in your bone marrow from special cells called stem cells. These do have a nucleus, but as the red blood cell develops the nucleus is squeezed/taken out. This makes more room for the red pigment haemoglobin, which is needed to carry the Oxygen in the red cells. Haemoglobin also carry's Glucose needed for energy and also they take Carbon Dioxide away from the cells to be breathed out through the lungs
What is the only human cell without nucleus?
Red blood cells (erythrocyte) do not contain nuclei. In case you're wondering where the DNA they get from a blood sample comes from, it is taken from the white blood cells (leukocytes) which do contain nuclei.

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
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 of your body's cells contain DNA?
red blood 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.
Which body cells don't make DNA?
Red Blood cells.
Where can you not get DNA from?
dna isn't found in red blood cells
What human cells can't have DNA extracted?
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.
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 red blood cells have DNA?
They do. Mammals are the only vertebrates without a nucleus in their erythrocytes.

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
Is there DNA in a cell?
No cells are not part of DNA. nucleotide bases make up DNA.
