报告摘要

Abstract: A central focus of genomic biology is to identify all genes, regulatory elements, and other functionally important features in the genome. Estimates of the total fraction of DNA that is under purifying selection are of interest inasmuch as they suggest the magnitude of the experimental effort that will be necessary to elucidate all functional elements.  Over the last decade, analyses of mammalian genomes have led to the widely accepted view that at least 5% of the human genome -- 150 megabases -- is functionally constrained (the rest being 'junk'), and some recent estimates have been substantially higher. I will discuss a number of issues related to the notion of 'functional', and present several lines of argument suggesting that the correct value is much lower (100 MB or less).
