Multiple Choice
In an overview of the cell cycle, what is the term for the period between successive cell divisions (mitoses) when the cell grows and replicates its DNA?
A
G0 phase
B
Interphase
C
M phase (mitotic phase)
D
Cytokinesis
Verified step by step guidance1
Understand that the cell cycle consists of distinct phases that prepare a cell for division and then execute the division process.
Recognize that the period between successive mitotic divisions is when the cell is metabolically active, growing, and replicating its DNA in preparation for mitosis.
Recall the main phases of the cell cycle: G1 phase (cell growth), S phase (DNA synthesis), G2 phase (preparation for mitosis), and M phase (mitosis).
Identify that the combined duration of G1, S, and G2 phases is called Interphase, which is the phase where the cell grows and duplicates its DNA.
Note that other options like G0 phase represent a resting state, M phase is the actual mitosis, and cytokinesis is the division of the cytoplasm, so the correct term for the growth and DNA replication period is Interphase.
