Answer 1

all cells have DNA except red blood cells

Answer 2

I am pretty sure red blood cells do not have a nucleus and thus don't contain DNA. However you also have white blood cells in you blood which do contain DNA.

Answer 3

No

DNa can only be found in chromosomes chromosomes are found in nuclei. Blood do not have nucleus and therefore, do not contain DNA.  

Answer 4

Young red blood cells contain DNA but as they mature they lose their nuclei so they're able to carry more oxygen.

White blood cells contain DNA.

Answer 5

Yes it does. So does hair, fingernails, eye skin, and flakes of skin.

Answer 6

Absolutely yes.  There are a host of genetic tests on the market today for detecting everything from parentage to the likelihood of having an inherited susceptibility to cardiac arrhythmia's.  The best source for DNA is a blood draw since other sources, such as buccal swabs often contain DNA of lower quality.
