Question

Quizplus · Accepted Answer

The human genome has approximately 20,000 protein-coding genes, as determined by the Human Genome Project. The other options are incorrect as they either refer to the number of genes in other genomes (corn and mouse) or provide an irrelevant answer (the size of the human genome in base pairs).
