Question

Quizplus · Accepted Answer

A gene is a specific segment of DNA that codes for a particular trait or function. It contains the instructions for making a specific protein, which can then affect an organism's physical characteristics or behavior. A nucleotide is a basic building block of DNA, while a nucleotide base pair is two complementary nucleotides that are paired together in the DNA double helix. All of the DNA contained on a specific chromosome includes many different genes, as well as non-coding regions and regulatory elements. Therefore, the best choice for a gene is option C.
