Open in App
Solution
The correct option is A 30,000
Human genome has approximately 21,000 genes in its 3.3 billion base pairs haploid genome. The haploid DNA content of a cell is called C-value. C-value is constant for a species; thus all humans have around 21,000 genes. Presence of large amount of base pairs is explained on the basis of large amount of structural DNA and junk DNA in chromosomes. Thus option B is correct answer.
