Can DNA testing be carried out on red blood cells alone?

Answer 1

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.

Answer 2

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.
