The number of proteins in humans
A)is approximately equal to the number of genes.
B)cannot be determined because the human genome is too complex.
C)is less than half the number of genes.
D)is much greater than the number of genes.

Question

Quizplus · Accepted Answer

The number of proteins in humans is much greater than the number of genes, as a single gene can code for multiple proteins due to alternative splicing, post-translational modifications, and protein-protein interactions. Additionally, some proteins are encoded by multiple genes. Therefore, the number of proteins is not limited by the number of genes in the human genome.
