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.
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.
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.
