Multiple Choice
In a typical proliferating mammalian cell, which phase of the cell cycle is usually the longest?
A
G1 phase
B
S phase
C
G2 phase
D
M phase (mitosis and cytokinesis)
Verified step by step guidance1
Understand the phases of the cell cycle: G1 (first gap), S (synthesis), G2 (second gap), and M (mitosis and cytokinesis). Each phase has a specific role in cell growth and division.
Recall that the G1 phase is the period after cell division where the cell grows and prepares for DNA replication, making it a critical phase for cell size and function.
Recognize that the S phase is when DNA replication occurs, which is essential but typically shorter than G1 because it involves copying the genome.
Note that the G2 phase is a preparation phase for mitosis, where the cell checks for DNA damage and prepares the necessary components for division, usually shorter than G1.
Understand that the M phase (mitosis and cytokinesis) is the actual process of cell division, which is relatively brief compared to the other phases, especially G1.
