How valuable are red blood cells in DNA typing?
Red blood cells do not contain a nucleus, which means they lack DNA. As a result, red blood cells are not useful for DNA typing. Instead, white blood cells, which do contain DNA, are typically used for DNA profiling and typing in forensic analysis.
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
Is there a cell in humans that don't have DNA?
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.
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
Is DNA found in RBC and WBC?
You have about 25 trillions of RBC in your blood. They do not have nucleus in them and so no DNA. WBC has a nucleus and contains the DNA.

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
Which body cells have no nuclear DNA?
mature Red Blood cells have no nucleus so no nuclear DNA present :)
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 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.
If DNA is made in the nucleus of a cell where is the nucleus in our blood?
Assuming the question is about red blood cells, the nucleus is no where. DNA is not necessary for red blood cells, their only function is to carry oxygen and carbon dioxide for and from cellular respiration, respectively. Since DNA is necessary mostly for cell division, red blood cells don't have it. Instead of dividing they are replaced on a regular basis. Red blood cells are instead manufactured in bone marrow. White blood cells contain their own set of DNA for division.
What do red blood cells need for DNA syntheses?
oxygen
