Detailed explanation-1: -In 2003, two years ahead of schedule, scientists announced that the human genome had been sequenced with an accuracy of 99.99 per cent. It was described as ‘the end of the beginning’.
Detailed explanation-2: -The Human Genome Project, completed in 2003, covered about 92% of the total human genome sequence.
Detailed explanation-3: -The Human Genome Project (HGP) was declared complete in April 2003. An initial rough draft of the human genome was available in June 2000 and by February 2001 a working draft had been completed and published followed by the final sequencing mapping of the human genome on April 14, 2003.
Detailed explanation-4: -In humans, only about 2% of the genome encodes proteins. Much-but not all-of the remaining 98% is evolutionary detritus. In the 1960s, researchers learned that non-coding DNA can serve vital functions, such as regulating gene action and building ribosomes.
Detailed explanation-5: -"Gene index analysis of the human genome estimates approximately 120, 000 genes, ” Nat. Genet.
