Answer:Each length of DNA that codes for a specific protein is called a gene. For instance, one gene codes for the protein insulin, the hormone that helps control levels of sugar in the blood. Humans have around 20,000–30,000 genes, although estimates vary.
Explanation:
The DNA sequence that houses the information to make a protein is called a gene. Each group of three bases corresponds to specific amino acids, which are the building blocks of proteins. For example, the base pairs T-G-G specify the amino acid tryptophan while the base pairs G-G-C specify the amino acid glycine.
