Answer:
C. a sequence of nucleotides in DNA that codes for a functional product.
Explanation:
A gene is referred to as a nucleotide sequence in DNA that codes for the synthesis of a functional product such as an RNA or a protein. It is also referred to as the functional and basic unit of hereditary. A gene is also found on a chromosome and differs from DNA because a DNA just comprises nucleotides and is found in the cell nucleus.
Genes carry genetic information which can be transferred to the offspring from the parents. These genetic information could be the color of the hair, height, color of the eyes and other traits that can be passed from parents to offspring.
