G1 Phase
Multiple Choice
In the cell cycle, what is the major event that occurs during the G1 phase?
A
The cell replicates its DNA, producing sister chromatids for each chromosome.
B
The cell undergoes cytokinesis, splitting the cytoplasm into two daughter cells.
C
The cell grows and synthesizes proteins and organelles to prepare for DNA replication.
D
The cell separates sister chromatids and divides its nucleus during mitosis.
검증된 단계별 안내1
Understand the phases of the cell cycle: G1, S, G2, and M phases, each with distinct events.
Recall that the G1 phase is the first gap phase after cell division, where the cell prepares for DNA replication.
Identify that during G1, the cell grows in size and synthesizes proteins and organelles necessary for the upcoming S phase.
Note that DNA replication occurs in the S phase, not in G1, so sister chromatids are produced later.
Recognize that cytokinesis and nuclear division happen during mitosis (M phase), not during G1.
