What is the haploid content of human DNA?

Options

  1. A5386 nucleotides
  2. B48502 base pairs
  3. C4.6 x 10⁶ base pairs
  4. D3.3 x 10⁹ base pairs

Correct answer

D. 3.3 x 10⁹ base pairs

Step-by-step solution

DNA is a long polymer of deoxyribonucleotides. The length of DNA is usually defined as the number of nucleotides (or a pair of nucleotides referred to as base pairs) present in it. This also is the characteristic of an organism. For example, a bacteriophage known as φ ×174 has 5386 nucleotides, Bacteriophage lambda has 48502 base pairs (bp), Escherichia coli has 4.6 × 106 bp, and haploid content of human DNA is 3.3 × 10⁹ bp . Let us discuss the structure of such a long polymer.
