List the salient features of the Human Genome

Explanation

1. The human genome contains 3164.7 million nucleotide bases .
2. The average gene consists of 3000 bases .
3. The largest known human gene being dystrophin at 2.4 millions bases .
4. The total number of gene is estimated ar 30000 .
99.9 percent nucleotide base sesquences are same in all the people .
5. The function of 50 %genes discovered is still unknown .
6. Less than 2 percent of the genome , codes for proteins.
7.Repeated sequences make up very large portion of human genome .
8. Chromosme I has the most genes (2968) and Y has the fewest (231) .
9. It is identified about 1.4 million lactions where single - base DNA difference ( SNPs-single nucleotide polymorphism ) occur in humans.
