Question

how do cells become specialized? (1 point) genetically identical cells undergo differentiation to make them genetically unique. mitosis creates genetically unique cells that can do different tasks. genetically identical cells undergo differentiation to alter gene expression. mitosis creates specialized cells for different purposes.

Explanation:

Cell specialization occurs through differentiation. Differentiation is a process where cells, which are initially genetically identical (from mitosis, which produces genetically identical cells), change in structure and function. This is due to changes in gene expression (not changes in the genetic code itself). Mitosis produces genetically identical cells, not genetically unique ones. Specialized cells' specialization is from differentiation altering gene expression, not mitosis directly creating specialized cells for different purposes.

Answer:

Genetically identical cells undergo differentiation to alter gene expression.
