Question

Quizplus · Accepted Answer

A gene is a portion of a DNA strand that functions as a hereditary unit and codes for a specific protein. This means that a gene contains the instructions for making a specific protein, which ultimately determines an organism's traits and characteristics. The sequence of nitrogenous bases along the DNA strand determines the sequence of amino acids in the protein.
