Question

why is DNA located in our fingerprints?

Answer 1

the DNA is located everywhere in our body. Our fingerprints are not DNA. But the skin that is in our fingers does have DNA. But also our fingerprint are unique!!

Answer 2

Yeah, just to clarify, your fingerprints aren't DNA. DNA is found in every cell of your body and codes for your eyes, your toenails, your bones, hair, everything. So in that sense, DNA is in your fingerprints.

You can identify someone by their fingerprints and DNA because everyone's fingerprints and DNA is unique.

Answer 3

There is DNA in your finger print because whenever you move or touch something, dead skin cells containing your DNA come off. One of the reasons your finger prints are left in the first place is the dead skin cells being left behind.

Answer 4

It is in the body oil that your fingers secrete. But they do not normally identify you by your DNA there. They can identify you with the imprint pattern that your fingers leave. It is a unique imprint and supposedly nobody has exactly the same fingerprint. z

Answer 5

Because skin cells are constantly being left behind and every single cell in the body (and those that fall off it) contain a full set of DNA

Answer 6

There are plainly some vocab difficulties going on here.

Literally interpreted, some DNA probably does end up in our fingerprints. Dead skin cells rub off as we touch things and those skin cells contain our DNA. Three people explain this well.

There is also another term - DNA fingerprinting - which you might be confused about. As Kainui aptly explains, DNA finngerprinting involves taking DNA from a sample (for example, one obtained at a crime scene) and matching it to DNA from one of a number of possible sources or suspects.

Answer 7

Actually we are coated with DNA and RNA, I would say it is part of the innate immune system as this protects us against viruses, at least this is what my old professor stated, as he has a doctorate in biochemistry I tend to believe him.
