Does mammalian blood contain any DNA?
Yes, mammalian blood contains DNA from the cells it carries. White blood cells, which are part of the immune system, contain DNA, and when they break down, the DNA is released into the blood. This can be useful in forensic investigations or medical diagnostics.
Which part of a blood cell is used for DNA profiling?
The white blood cell is used for DNA profiling as it contains the nucleus which houses the DNA. Red blood cells do not have a nucleus or 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?
No, DNA testing requires a white blood cell sample because red blood cells do not have a nucleus, which is necessary for DNA analysis. White blood cells contain a nucleus where DNA is located, making them suitable for DNA testing.
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 blood cells have DNA, which carries genetic information and is important for cell functions. White blood cells, red blood cells, and platelets all contain DNA, although red blood cells lose their nucleus during maturation and do not have a nucleus with 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?
No, red blood cells (RBCs) do not have a nucleus or organelles and do not contain DNA. White blood cells (WBCs) do contain DNA because they have a nucleus.
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
