Mature red blood cells do not contain DNA! Part of their maturation is expelling the nucleus (and DNA within) to make more room for hemoglobin. White blood cells have nuclei and DNA within. In some of them (B lymphocytes) there are some rearrangements of DNA during synthesis of immunoglobulines (each cell line shall secrete only certain types of protein chains for immunoglobulines and shall keep the genes for only that type of Ig). Regarding proteins, there are manydifferencess, since red blood cells contain hemoglobin mainly, and white blood cells produce a bunch of proteins (Ig, cytokines, etc.).

Blood is an excellent source of human DNA. DNA is present in white blood cells of humans, but not red blood cells which lack nuclei. A dime-sized spot of blood, approximately 50 µl in volume, is enough DNA for a typical VNTR analysis. That's why when you see a picture of a blood they have holes like a donut.

it has been stated that DNA is only found in white
blood cells as opposed to red blood cells.
There are mutliple questions here, each of which would require quite a bit
of explanation to respond completley. First off, red blood cells as alluded
to, have no nucleus and no DNA.

Yes, white ones do. Red blood cells do not. Red cells toss all that stuff during development and are big bags of hemoglobin.

Yes. But I don't think red blood cells do.

yes they do,white blood cells=leukocytes. WBC contain DNA.
Red blood cells dont have dna because they have no nucleus.

Yes, but red blood cells don't since they also lack a nucleus.

Yes, white cells have DNA; it's the red cells which do not.

All blood cells have DNA. Dna is part of the blood cell.

its a cell, as in a living organism of the body. I would say YES.
