Answer» Slient features of humen genome (i) The humen genome contains 3164. 7 million nucleotide bases. (ii) The average gene consists of 30000 the largest know humen gane being dystrophin at 2.4 Million bases . (iii) The total number of genes is estimated to be 30000 and 99.9% nuceotide bases are exactly the same in all people. (iv) The functions are unknown for over 50% of the discovered genes. (v) Less than 2% of the genome codes for proteins. (vi) The humen genome contains large repeted sequences . (vii) The repeated sequence is through to have no direct coding functions but they throw light on chromosomes struction , dynamics and evolution . (viii) Chromosome I has most genes (2968) and the Y has the fewest genes(231) (ix) Scientists have identified about 1.4 million location where single base DNA sequence differences called SNPs or Single Nucleotide Polymorphisms occur in humans. |
