Question

What is the approximate genome size of the human haploid genome?

Options

• ~48,502 bp

• ~5,386 bp

• ~3.3 × 10⁹ bp

• ~4.6 × 10⁶ bp

Answer 1

The human haploid genome (one complete set of chromosomes) contains approximately 3.3 billion base pairs (3.3 × 10⁹ bp). This is vastly larger than bacterial genomes and bacteriophage genomes, reflecting the greater genetic complexity of multicellular eukaryotes. The human diploid genome (containing two sets of chromosomes, one from each parent) would be approximately twice this size.
