Scientists expected to find as many as 100,000 genes packed into the 3 billion bases of human DNA; they were startled to learn that there were fewer than 35,000. (The current count is 21,000.) Protein-coding regions accounted for just 1.5% of the genome. Could the rest of our DNA really just be junk?Р1、基因组研究РNoncoding sequences: Sequences in genome, which are not coding for any proteins.
