DNA is the hereditary molecule that determines hair color in humans. However, the DNA molecule itself is colorless. How does DNA determine the hair color of individuals?

This question lacks options, the options are:

A. The sequence of DNA determines the structure of lipids, which produce phenotypes.

B. The sequence of DNA determines the structure of proteins, which produce phenotypes.

C. The sequence of DNA determines the structure of phosphates, which produce phenotypes.

D. The sequence of DNA determines the structure of carbohydrates, which produce phenotypes.

The answer is B.

Explanation:

DNA is the genetic material found in the genome of living organisms. DNA holds the information needed for the synthesis of useful products in an organism. DNA contains segments called GENES that encodes the biological molecule, PROTEINS, which is responsible for the trait exhibited by organisms.

An example of trait in humans is human color, which is encoded by DNA. However, this DNA does not directly produce hair color in humans but the information held in it undergoes expression to produce protein called MELANIN, which is responsible for the hair color trait. Hence, the sequence of DNA determines the structure of proteins, which produce phenotypes (hair color).
