UNIT 7 LESSON 4 Mitosis Mitosis in Complex Organ Mitosis in Complex Organisms Quick Check How do cells become specialized? (1 point) Genetically identical cells undergo differentiation to make them genetically unique. Mitosis creates specialized cells for different purposes. Mitosis creates genetically unique cells that can do different task. Genetically identical cells undergo differentiation to alter gene expression.

The answer is the last one: Genetically identical cells undergo differentiation to alter gene expression.

Explanation for each option:

1. Genetically identical cells undergo differentiation to make them genetically unique.

   • This is incorrect. Differentiation does not change the genetic code of the cells; it changes which genes are expressed.

2. Mitosis creates specialized cells for different purposes.

   • This is incorrect. Mitosis is the process of cell division that results in two genetically identical daughter cells. It does not directly create specialized cells.

3. Mitosis creates genetically unique cells that can do different tasks.

   • This is incorrect. Mitosis produces genetically identical cells, not genetically unique ones.

4. Genetically identical cells undergo differentiation to alter gene expression.

   • This is correct. Differentiation is the process by which cells become specialized. Although the cells are genetically identical, differentiation alters gene expression to enable the cells to perform specific functions.

Summary: Cells become specialized through the process of differentiation, where genetically identical cells alter their gene expression to perform specific functions.
