Well, the question is general so answers could be general As an example, seems that we know a lot about the part of dna that codifies (about 1.5 percent). But what about the rest? At which point we are in understanding regulatory sequences and what in general is called junk-dna? Which knowledge we have in the effect of changing a gene expression and the effect it has on the phenotype? And know if changing a single gene let the dna in, how could I say, "coherent" state.

Hello, since often this topic is discussed in terms of percentage, and science writers speaks with very different terms on that subject , I would like to know at what point knowledge of the dna is and what are next milestones (and obstacles) to understand fullfill how dna works and, in particular, how human dna works. Thanks, wily
