Question

Why are kidney cells, skin cells, and brain cells so different from one another in form and function?

Each cell type contains a unique genome

Kidney cells are triploid, skin cells are diploid, and brain cells are haploid

Each cell type possesses different chromosomes

Although all genes are present, only certain genes are expressed in each cell type

Answer 1

The correct option is although all genes are present, only certain genes are expressed in each cell type.

Different cells have distinguishing functions. This is because of differential gene expression. This is regulated by hormones and other messengers that trigger the transcription and translation of specific genes to produce specific proteins that regulate and justify the functionality of the cell.

Each cell has same genome. So, first option cannot be correct.

Somatic cells of the body are usually diploid, however, very few cells exhibit aneuploidy. So, second option cannot be correct.

All cells possess same chromosomes. So third option cannot be correct.
