Explanation:

A section of DNA that provides information for a protein is called a gene.

The gene is nothing more than a specific sequence of DNA that contains the instructions needed to synthesize a protein or RNA molecule. We can say that the gene is the fundamental unit of heredity. Generally, genes with letters of the alphabet are represented.

All cells in a body have the same genes; however, in some cells, one type of gene is activated and another is deactivated, thus ensuring cell differentiation. It is worth noting that, in some cases, the gene is activated at all times, as they are fundamental for performing basic cell activities.

the fossil record provides evidence of a common ancestor to many species.
