Question

The model shows steps involved in the eukaryotic cell cycle.

A cell containing four strands line up along the middle of the cell. The cell is pinched in the center and each side of the cell contains two strands. Two cells are produced, each with two strands.

Which best describes what is occurring in the model?

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

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

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

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

Answer 1

D

This shows mitosis (chromosomes lined up at the metaphase plate, separated and the cell dividing), producing two genetically identical daughter cells.
