Answer:
DNA
Step-by-step explanation:
Nearly every cell in a person's body has the same DNA (when we are talking about somatic cells). However, different genes are expressed based on epigenetic factors. The cells inside our bodies are "specialized ". This means that each type of cell performs a unique and special job. Because of this, each of the different types of cells has a different structure, size, shape, and function. For example, lung cells are different from skin cells because of the proteins they create. Reproductive cells, though they have the same DNA, they only contain a portion of it due to meiotic division.
