Final answer:
Humans have approximately 20,000 to 25,000 genes in their bodies, a number that enables the production of numerous proteins through processes like splicing, despite being a modest count when compared to some other species.
Step-by-step explanation:
Approximately 20,000 to 25,000 genes are present in the human body, according to various scientific estimates. Even though this might seem like a large number, it is relatively modest when compared to other species, some of which have nearly as many genes.
Despite having a lower count of genes, humans can produce a vast array of proteins due to the processes such as splicing, allowing a single gene to encode instructions for multiple proteins. The human genome comprises approximately 3 billion base pairs, of which only about 25 percent make up genes and their regulatory elements, and just 1.5 percent encode for proteins.
