Overview of the Cell Cycle
Multiple Choice
In the overview of the eukaryotic cell cycle, which event primarily occurs during the G2 phase?
A
Chromosomes align at the metaphase plate and sister chromatids attach to spindle microtubules
B
DNA is replicated to produce two complete copies of the genome
C
The cell divides its cytoplasm to form two daughter cells (cytokinesis)
D
The cell grows and prepares for mitosis by synthesizing proteins and checking/repairing replicated DNA
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 S phase, DNA replication occurs, producing two complete copies of the genome.
Recognize that during mitosis (M phase), chromosomes align at the metaphase plate and sister chromatids attach to spindle microtubules, followed by cell division.
Focus on the G2 phase, which occurs after DNA replication and before mitosis; during this phase, the cell continues to grow and synthesizes proteins necessary for mitosis.
Also note that the G2 phase includes important checkpoints where the cell checks and repairs any DNA damage to ensure the genome is intact before proceeding to mitosis.
