Overview of the Cell Cycle
Multiple Choice
In the context of the eukaryotic cell cycle, which of the following occurs during cell division (mitosis followed by cytokinesis)?
A
Sister chromatids separate into two nuclei and the cytoplasm divides, producing two daughter cells
B
DNA is replicated to form identical sister chromatids (S phase)
C
The cell grows and synthesizes proteins in preparation for DNA replication (G1 phase)
D
Cells exit the cycle into a quiescent, nondividing state (G0 phase)
Verified step by step guidance1
Understand that the eukaryotic cell cycle consists of several phases: G1 (cell growth), S (DNA replication), G2 (preparation for mitosis), and M (mitosis and cytokinesis).
Identify that DNA replication to form sister chromatids occurs during the S phase, which is before mitosis and not part of cell division itself.
Recognize that the G1 phase involves cell growth and protein synthesis, preparing the cell for DNA replication, but it is not the phase where cell division happens.
Know that the G0 phase is a resting or quiescent state where cells exit the cycle and do not divide, so no cell division events occur here.
Focus on the M phase, where mitosis occurs: sister chromatids separate into two nuclei, followed by cytokinesis, where the cytoplasm divides, resulting in two daughter cells.
