Multiple Choice
In an overview of the eukaryotic cell cycle, what best describes the G0 phase?
A
The period of cell growth and preparation for mitosis that occurs after DNA replication is complete
B
A quiescent (non-dividing) state in which a cell has exited the cycle from G1 and is not actively progressing toward DNA replication or mitosis, though it may re-enter the cycle in response to signals
C
The phase in which DNA is replicated to produce sister chromatids
D
The stage of mitosis during which chromosomes align at the metaphase plate
Verified step by step guidance1
Understand that the eukaryotic cell cycle consists of several phases: G1 (gap 1), S (synthesis), G2 (gap 2), and M (mitosis). Each phase has distinct cellular activities.
Recognize that the G0 phase is a specialized state where cells exit the active cycle, meaning they are not preparing for DNA replication or mitosis.
Note that cells in G0 are considered quiescent or non-dividing, but they can potentially re-enter the cell cycle if stimulated by certain signals.
Differentiate G0 from other phases: G1 is for growth before DNA replication, S phase is for DNA replication, G2 is preparation for mitosis, and M phase is where mitosis occurs.
Conclude that the best description of G0 is a resting or quiescent state outside the active cycle, distinct from phases involving DNA replication or mitosis.
