In the context of the cell cycle, the G1 and G2 phases are primarily associated with growth and preparation for mitosis, rather than direct cell division or nuclear division. Here's a breakdown:
-
G1 Phase (Gap 1): This phase involves cell growth, organelle duplication, and preparation for DNA replication. The cell increases in size and synthesizes various proteins needed for subsequent phases.
-
S Phase (Synthesis): This is where chromosome replication occurs, as cells duplicate their DNA in preparation for cell division.
-
G2 Phase (Gap 2): This phase follows the S phase and is another growth period where the cell prepares for mitosis by synthesizing proteins and organelles required for cell division. The cell also checks for any DNA damage before proceeding to enter mitosis (M phase).
So the correct answer pertaining to the G1 and G2 phases of the cell cycle is:
c – growth.
