Can scientists change a person's DNA? Replace it with a new DNA?

Question

It can and should be DNA that's not assigned to anyone.

Answer 1

Yes its possible. Some viral vectors can be loaded with the required DNA sequence and targeted on host. But the 100%replacement of DNA is not possible because it will depend upon the severity of the infection by the vector and people have different level of immune system.

The idea is facinating but we will have to go long way. This process is called transduction.

Answer 2

DNA is something that we get from our mother and father that can never change no matter how scientist do theirs best to play God or the Creator of Life as some will say

Answer 3

scientists spice different dna together. like the sheep that are whatever % human recently created. the pigs that glow in the dark (pigs sliced with jellyfish I believe).

it isn't like they could take a grown human being and replace their cancer-causing genes though, it has to be done before the organism is grown

Answer 4

The last person that they tried to do it on died in PA (look up Jesse Gelsinger). They tried to replace a gene (gene therapy) using a couple of viruses (adenovirus and parvovirus). Theoretically it should of worked, but the body went into hyper-acute rejection from the viruses. That's the reason why gene-therapy is on hold indefinitely.

Answer 5

now-a-days, it might be possible to replace dna but only with the cloning of its original...but not changing the dna

Answer 6

That makes me wonder about organ transplants and DNA.

Answer 7

I don't think so because there is DNA in every single cell, and there are many, many, many cells in your body, so modifying each of those would be extremely hard.

Answer 8

No....although they can confuse it ! especially at a bias court case !!

Answer 9

No, they cant, technology has not gotten to that point.

Answer 10

We are NOWHERE near being able to do that!
