A
DNA replication takes place.

Chromosomes are aligned in the center of the cell.
C
The cell undergoes cytokinesis.
D
The cell grows and synthesizes proteins.
Verified step by step guidance1
Understand that the cell cycle is divided into several phases: G1, S, G2, and M. Each phase has distinct functions and processes.
Recognize that the G1 phase, also known as the first gap phase, is the period in the cell cycle where the cell grows and carries out normal functions.
During the G1 phase, the cell increases in size and synthesizes various proteins and organelles necessary for DNA replication and cell division.
Note that DNA replication does not occur during the G1 phase; it takes place in the S phase (Synthesis phase) of the cell cycle.
Understand that cytokinesis, the process of cytoplasmic division, occurs after mitosis in the M phase, not during the G1 phase.
