Which part of a blood cell is used for DNA profiling?
The DNA in the nucleus, although this would need to be a white blood cell as red blood cells have no nucleus, instead using the space to store oxygen.
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.
First isolated DNA using pus collected from bandages at a local hospital since white blood cells are a major component of pus they were your source of DNA?
It is not ideal to isolate DNA from pus collected from bandages as it may contain contaminants from the wound environment. Using white blood cells obtained from a blood sample would provide a purer source of DNA for isolation techniques. This can be done by extracting white blood cells from the blood sample and isolating DNA from these cells using appropriate methods.
Can DNA testing be carried out on red blood cells alone?
It depends on the organism you're talking about and what kind of DNA. A mammilial red cell does not have nucleus, so most DNA testing is impossible. However, it does have mitochondria, which contain their own DNA, and testing can be done on this.
Why doesn't different cells have different DNA?
Different cells have different parts, depending on their job in the body. That's why red blood cells differ from white blood cells; a red blood cell has mitochondria and vacuoles. The white one does not.
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
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
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
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.
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.

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 are white blood cells often used to study a persons genes?
because they are the only blood cells with a core .That means that they have dna
