What specializations might allow one tissue to produce a hormone, and another to facilitate nutrient exchange? is it possible fo
noname [10]

Differential gene expression patterns allow one tissue to produce a hormone, and another to facilitate nutrient exchange. The same organ can serve both functions because it can synthesize different proteins.

<h3>Diferential gene expression</h3>

Gene expression refers to the differential process by which different genes are expressed (transcribed and then translated) in different cell types.

Gene expression enables different functions due to the production of different types of proteins which may have both enzymatic and structural functions.

A specialized cell type or organ can synthesize different proteins and also generate other molecules (either enzymes or structural proteins) due to the process of cell differentiation.
