Is the gene((s) (?)) insertet in a female mouse, than it's ...

Some pretty good answers here, thanks! Is it so that DNA is instructed to make leathal mutations (cancer) at "a late stage" in a Gene- host's life? I think it's a pretty big sacrifice for our genes to destroy it's host- body (in humans today at least), becouse only 50% of a parents gene's ...

Re: I need a scientific magazine

Thanks!

Will consider both mags.

Any magazine out there consentrating mainly on biology? I don't think I would have much use of a magazine explaining the latest worm- hole- theory with alot of complicated equations :lol:
