The haploid content of human DNA is

Question

The haploid content of human DNA is (A) 3.3× 106bp (B) 3.3× 109bp (C) 4.6× 106bp (D) 6.6× 109bp

The human genome is a complete set of nucleotide sequences present in the 23 pairs of chromosomes in the cell nuclei. The haploid genome, which is found in the germ cells, like sperms and eggs, before the formation of a diploid zygote, consists of nearly 3 billion DNA base pairs. It is approximately 3.3x109 base pairs or 3.3 GB for the haploid genome, and double the amount or 6.6x109 base pairs or 6.6 GB in the diploid genome. It is also interesting to know that 1GB DNA has a mass of nearly 1pg (the average molar weight of a base-pair, 660 g/mol), thus, the diploid (2n) human cell hat a DNA content of 6.6 pg. There are 23 pairs of chromosomes, contain more than 20000-25000 genes in human. The genome size of the E. coli, a common bacterium is nearly 4.6x106 base pairs.
