The expression of some genes within one cell, but a different expression of the same set of genes within another cell refers to __________.

A) gene expression
B) phenotype
C) genome biochemistry
D) protein activation

Gene Expression

The process by which information from a gene is used to synthesize a functional gene product, often proteins, influencing the cell's structure and function.

Phenotype

The collection of traits that can be seen in a person, which emerge from the way their genetic makeup interacts with their surroundings.

Protein Activation

The process by which proteins are enabled to perform their specific biological functions, often through structural changes or binding to other molecules.
