Which of the following best explains why the two rat cell types are different?
Choose 1 answer:

(Choice A)
Because the cells have undergone mitosis, the adipocyte and the astrocyte contain different genes.

(Choice B)
Because of differential gene expression, the adipocyte and the astrocyte produce different proteins.

(Choice C)
Because the cells are the result of a fertilization event, the adipocyte and the astrocyte contain different chromosomes.

Answer 1

The statement 'due to differential gene expression, the adipocyte and astrocyte produce different proteins' explains why the two rat cell types are different.

What is gene expression?

Gene expression can be defined ad the differential process by which certain genes are transcribed in one cell type.

Gene expression leads to cellular specialization to perform specific works in the multicellular body.

Gene expression is a fundamental process for the development of multicellular organisms.
