Facts but not sure about the prove.?

Question

My friend told me that a DNA of a chameleon can change the color of a human hair if that DNA is injected into the human body. I tried looking into the internet but I found nothing. Is it true? If it is true, please tell me the website.

Answer 1

Only 3% of DNA inside human body is actually essential. Others are just junk DNA that doesn't do much. That's why when a virus that goes through the lytic cycle injects its DNA/RNA into a host cell its DNA can become part of the cell without changing the 3% of the of the essential DNA that may affect the entire function of the cell, tissue, or organ (lytic viruses don't intend to kill its host cell or else it wouldn't be able to manufacture more viruses in the future).

So even if a piece of Chameleon DNA is injected into the human body nothing's gonna happen. The body attacks foreign material, not receive it. So it's not true. In fact, even if you DID inject and it DOES change the DNA you can't be sure it'll go to the DNA part (trait) that determines the hair color and be able to modify it anyway. A different DNA of a different animal won't function properly inside another one with completely different DNA (there are very few exceptions, like virus but then Virus actually knows what its doing and how to do it).

Even if you inject a guy with brown hair into a guy with black hair that guy with black hair won't get brown hair.

Answer 2

That isn't true.  DNA is inside every cell in your body, if you inject a different type of DNA, it won't change all the rest of the DNA in your body.  The only thing similar to this we've been able to do is replace certain portions of a single-celled bacteria's DNA in order to, for example, produce a certain chemical.  THEN the modified bacteria is allowed to multiply.
