Answer:
C. Gene
Explanation:
The gene is a segment of a DNA (deoxyribonucleic acid) molecule responsible for genetically inherited traits. Each gene consists of a specific DNA sequence that contains a code (instructions) to produce a protein that performs a specific function in the body.
Most genes are contained in chromosomes. The chromosome consists of a long strand of DNA wrapped around a special protein called histone. Most chromosomes contain several different genes. Human cells contain 23 pairs of chromosomes - one pair of sexual chromosomes (XX in women or XY in men) plus 22 pairs of nonsexual chromosomes called autosomes. Chromosomes are transmitted from parents to children through sperm and eggs. One chromosome from each pair is inherited from the mother and the other from the father.
