Question

Which best describes what is occurring in the model?



Responses

A. The cell is undergoing the S phase, where the cell rapidly grows and divides.

The cell is undergoing mitosis, not the S phase.
A. The cell is undergoing the S phase, where the cell rapidly grows and divides. The cell is undergoing mitosis, not the S phase.

B. The cell is undergoing the S phase, where the genetic material of the cell is copied.

The cell is undergoing mitosis, not the S phase.
B. The cell is undergoing the S phase, where the genetic material of the cell is copied. The cell is undergoing mitosis, not the S phase.

C. The cell is undergoing mitosis, where one cell splits into two genetically diverse daughter cells.

The cell is undergoing mitosis, where one cell splits into two genetically identical, not diverse, daughter cells.
C. The cell is undergoing mitosis, where one cell splits into two genetically diverse daughter cells. The cell is undergoing mitosis, where one cell splits into two genetically identical, not diverse, daughter cells.

D. The cell is undergoing mitosis, where one cell splits into two genetically identical daughter cells.

The cell process shown in the model is part of mitosis, where one parent cell divides to create two daughter cells, each containing genetically identical DNA.

Answer 1

D.

Mitosis is the process in which one parent cell divides to form two genetically identical daughter cells. (The S phase is the part of interphase when DNA is copied before mitosis; genetic diversity is a feature of meiosis, not mitosis.)
