It will be interesting. The biggest problem with cloning extinct animals is that DNA has no inherent meaning outside of a specific environment. The machine that reads the instructions is just as important as the instructions themselves. What a living, reproducing species has is a set of instructions that, when put in a specific machine (the cellular environment of the egg, and the environment that the embryo develops in), it creates an organism with that same machine, more or less. When you just take DNA, you have to hope you can find a machine close enough to the original that can actually follow those instructions the way you want it to. Theoretically, we could make an environment that reads mammoth DNA and spits out a toaster.
