how come we can't revive extinct animals like mammoth with DNA cloning?

It is in fact possible for us to get material from recently extinct animals to try and bring a species back so why aren’t we? I know this may be somewhat controversial but I cant help but wonder how bad this really could be? If we just cloned one extinct animal to learn from it, etc. I’m not talking about bringing back 1000’s of a species. Has this been done already, have any extinct or close to extinct animals been successfully cloned?

1. Because the fetal development depends in part on the environment it develops in too (i.e. the womb itself). With no original females left, as I understand it, the end product would not necessarily be the extinct creature.
2. also the DNA recovered is rarely complete and functional, DNA molecules degrade over time, so when we get it , it's rarely 100% intact moreover as you were told, a fetus needs a suitable womb to develop in, and as the species is extinct, no viable female are found to host the developing embryo. add to that, the DNA need to be put inside a matching living cell in order to start replicating, so wee need a good living cell which can host the DNA,and that is not found either.
3. The proccess which you are talking about is extremely similar to cloning (like Dolly the sheep) but cloning means putting the DNA of a sheep into a womb of a sheep. Since we have no living mammoths to give sperm or an egg, or the facilities to care for one on this earth, it is not possible for now :) hope I helped
