G1 Phase
Multiple Choice
In the context of the cell cycle, what best describes what happens when a cell enters the G0 phase from G1?
A
The cell replicates its DNA in preparation for mitosis.
B
The cell undergoes chromosome segregation and cytokinesis to produce two daughter cells.
C
The cell exits the active cell cycle and enters a quiescent, non-dividing state, often performing specialized functions and potentially re-entering G1 in response to signals.
D
The cell rapidly increases in size and synthesizes organelles as it prepares to pass the G1/S checkpoint.
Verified step by step guidance1
Understand the phases of the cell cycle: G1 (growth), S (DNA synthesis), G2 (preparation for mitosis), and M (mitosis).
Recognize that the G0 phase is a distinct state where the cell exits the active cycle and stops dividing.
Identify that when a cell enters G0 from G1, it does not proceed to DNA replication or mitosis but instead becomes quiescent.
Note that cells in G0 often perform specialized functions and can remain in this state for varying durations.
Remember that cells in G0 can sometimes re-enter the cell cycle at G1 in response to specific signals, resuming division.
