Multiple Choice
In the cell cycle, what does the G1 phase stand for and what occurs during this stage?
A
G1 stands for 'Gap 1', and it is the phase where the cell grows and synthesizes proteins.
B
G1 stands for 'Growth 1', and it is the phase where DNA replication occurs.
C
G1 stands for 'Gap 1', and it is the phase where the cell undergoes mitosis.
D
G1 stands for 'Growth 1', and it is the phase where the cell divides into two daughter cells.
Verified step by step guidance1
Understand that the cell cycle is a series of phases that a cell goes through to divide and produce new cells.
Identify the phases of the cell cycle: G1, S, G2, and M phase.
Recognize that G1 stands for 'Gap 1' phase, which is the first phase after cell division.
During the G1 phase, the cell grows in size and synthesizes proteins necessary for DNA replication.
Clarify that DNA replication does not occur in the G1 phase; it occurs in the S phase (Synthesis phase).
