Question

does DNA really die??!! If No is your answer ,why dont we get extinct animals or people back alive??!!!!

Answer 1

dont think of dna as alive or dead - think of it as a code for designing things (which can be destroyed). if you used dna to recreate someone, they wouldnt be alive again - they would only be a clone. and since experience plays a huge role in shaping who we are, those people couldnt even be exactly copied as they were when they died.
as for bringing a dead species back into existance - that's totally possible, albeit extremely cutting edge right now and has yet to actually be done.

Answer 2

We dont get extinct because of the fact that humans are a species that are able to adapt themselves to their surroundings - thats how we have survived over time. This is partly Darwin's theory of natural selection. (answer to your extinction bit)

Answer 3

extinct animals are extinct ... which means that their DNA's are not really fully available ... thus you cannot get them back ...

Answer 4

Many extinct animal's DNA is actually available. Just it is currently impossible to actually bring them back as they were. Cloning has only come so far, unfortunately you still need a living animal's gametes into which you can incorporate the extinct animal's DNA.

Your question is sort of confusing. I can't quite make out what you're asking, so here is a possible answer.
DNA is not technically alive, although in a sense it carries our life. One day it may be possible to bring extinct animals back. Unfortunately bringing people back to life is not possible. You could use the DNA to create a clone of them, but they would not be the same person. A person is quantified by their experiences. So while the clone would look just like whoever you wanted to bring back, they would not think or act the same.
You could clone Einstein and he could end up being dumb.

Answer 5

Yes DNA do die in many cases like necrosis and apoptosis, unless you argue that all the species emerged from a common ancestor. DNA are constantly formed and destroyed, same is the cases of cells containing them. Along with the death of human billions of DNA die and some pass on to his off spring through gametes. After all, DNA is a molecule and is it legitimate to ask if carbon dioxide dies? We all know it is formed as well as derived to other forms, continuously, in nature.

Answer 6

Well first of all nothing can be created or destroyed, you can only break matter down to a certain point, physically change it or chemically change it. DNA ( deoxyribonucleic acid) can be changed, but not just turned to nothing. DNA cannot "die" because for one it is not living, however it's unique code can become unviable.
