Document Summary
90% of our dna is transcribed into non coding rna: be able to describe the different categories of dna sequence. Companies now sequence genome in 1 week for. 5-6% of entire genome is protein encoding large proportion of regulatory sequences= primers, what noncoding sequences do in junk dna genome have important roles to play organisms theyre transcribed into rnas which increases with complexity of. Estimated number of genes keeps changing- before we sequenced human genome, estimated 45,000 then 33,000 in year 2000 in september 13, 2012. 20,687 protein coding genes, whose coding exons encompass about 5% of the genome. 11,224 pseudogenes of which 863 were transcribed and associated with active chromatin. Ezkurdia, multiple evidence strands suggest that there may be as few as 19000- 20000 human protein-coding genes: as the genome project progressed, the estimate for number of genes decreased, the number of non coding rnas has increased significantly, many genes belong to families based on homologous.
