Multiple Choice
In the eukaryotic cell cycle, what is a key event that occurs during the G2 phase?
A
Chromosomes align at the metaphase plate and attach to spindle microtubules
B
The nuclear envelope reforms and the cell completes cytokinesis to produce two daughter cells
C
DNA is replicated to produce two identical sister chromatids for each chromosome
D
The cell grows and prepares for mitosis by synthesizing proteins and checking that DNA replication is complete and undamaged
Verified step by step guidance1
Understand the phases of the eukaryotic cell cycle: G1 (growth), S (DNA synthesis), G2 (preparation for mitosis), and M (mitosis).
Recall that during the G2 phase, the cell has already completed DNA replication in the S phase, so DNA synthesis is not occurring in G2.
Identify that the G2 phase involves the cell growing further and synthesizing proteins necessary for mitosis, such as those involved in spindle formation.
Recognize that the cell also performs important quality control during G2, checking for DNA damage and ensuring replication is complete before proceeding to mitosis.
Distinguish G2 events from other phases: metaphase alignment occurs in M phase, nuclear envelope reformation and cytokinesis occur after mitosis, and DNA replication occurs in S phase.
