Multiple Choice
In the context of the cell cycle, what is the cell primarily doing while in the G0 (quiescent) state, relative to the G1 phase?
A
Undergoing rapid cell growth while committing to immediate entry into S phase
B
Carrying out specialized normal functions while remaining outside the active cell cycle and not preparing to divide
C
Actively replicating its DNA in preparation for mitosis
D
Separating sister chromatids and completing cytokinesis
Verified step by step guidance1
Understand that the cell cycle consists of several phases: G1 (first gap), S (DNA synthesis), G2 (second gap), and M (mitosis). Cells can also enter a G0 phase, which is a quiescent or resting state outside the active cycle.
Recognize that during the G1 phase, the cell grows and prepares for DNA replication, committing to enter the S phase where DNA synthesis occurs.
Know that the G0 phase is distinct from G1 because cells in G0 are not preparing to divide; instead, they have exited the active cycle and are performing their specialized functions.
Recall that cells in G0 maintain normal cellular activities but do not undergo DNA replication or mitosis, unlike cells in S phase or M phase.
Therefore, the primary activity of a cell in G0 is carrying out specialized normal functions while remaining outside the active cell cycle, rather than preparing for division.
