Dihydrofolate reductase, DHFR, is ...<b>About Average?</b><br /><br />Dihydrofolate reductase, <A HREF="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene&cmd=Retrieve&dopt=full_report&list_uids=1719">DHFR</A>, is an ancient "housekeeping" enzyme that moves a methyl group required for the synthesis of purines and some amino acids. DHFR gene is encoded in only about 3 kbp on 6 exons spread over about 30 kb (1 gene/30kb). This seems to be a sparse code. <br /><br />Even though this gene is huge, at this rate, a 3 Gb genome would encode 100,000 genes!<br /><br />The numbers: 3x10^9 bp/genome x 1gene/3x10^4 bp = 10^5 genes/genome.Reuelhttps://www.blogger.com/profile/00375847200584931533noreply@blogger.com
