On Earth, life encodes it genes using DNA. Is it safe to assume that on other planets life would begin differently, so therefore their genes would be encoded in a different way? Or is there some reason why we might think that DNA could be universal?<br /><br />Also, would the biology from two different planets be compatible? i.e. could they eat each other? could microbes from one planet infest beings from another planet?<br /><br />And (one more thing) if someone could travel to an alien 'Earth-like' planet and run some experiments on the local plant, microbial, and animal life - what kind of experiments might they perform?<br /><br />If anyone has a link to real research on the subject it would be much appreciated.
