How many nucleotide pairs comprise the human genome?

Question

Quizplus · Accepted Answer

The human genome is composed of 3 billion nucleotide pairs. This is a widely accepted estimate, and represents the total amount of DNA base pairs in a diploid human cell (i.e. containing two sets of chromosomes). Choice A is too low by several orders of magnitude, while choice D is far too high. Choice B is a particularly tricky distractor, as it is relatively close to the actual number of nucleotide pairs in the human haploid genome (i.e. a single set of chromosomes) - however, since humans are diploid organisms, the correct answer must be much higher.
