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.
Any cells can be used as you will find DNA in almost all of them (a few exceptions are red blood cells, platelets, etc.) but even where one specific cell in a tissue has no DNA many adjacent cells in the sample will have DNA.
None! If Any Did NOT Then They Would Be Completely Untraceable Even To Human And Technology Standards.
There is as much DNA in white blood cells as any other cell. There is none in red blood cells.
Most somatic cells and all gametes. (red blood cells do not contain a nucleus or any major organelle and therefore do not carry DNA and are not able to synthesize RNA, however during the early stages of red blood cell production in the marrow even they have DNA)
In whole blood transfusions... yes, but only a small amount. Red blood cells have no nuclei and therefore only mitochondrial DNA; white cells have nuclei but are present in much smaller numbers.
Yes, there is one type of cell which does not contain DNA, and that is the red blood cell.

Any secretion of you body that may contain cells of your body can be used to extract DNA.
The main cells in your body that contain DNA and RNA are your skin cells. This is because skin cells hold more then the DNA to skin. The DNA in skin also tells a person's eye color, height, hair color and bone structure. RNA in any cell is used to transfer any messages from one cell to another.
In whole blood transfusions... yes, but only a small amount. Red blood cells have no nuclei and therefore only mitochondrial DNA; white cells have nuclei but are present in much smaller numbers.
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
Prions are an infectious particle made of protein. They do not contain DNA or RNA.
Sources of DNA that can be used in DNA forensic analysis include blood, saliva, hair follicles, semen, skin cells, and bone fragments. These sources provide enough genetic material for analysis and can help in identifying individuals or solving crimes.
No, DNA is not found in any prions. Prions are just protein - they don't contain a nucleic acid.
