Quizplus · Accepted Answer

Although humans have about 20,000-25,000 genes, the number of proteins that can be produced is much greater as a single gene can code for multiple proteins through alternative splicing and post-translational modifications. Therefore, the number of proteins is much greater than the number of genes.
