What happens during the G1 phase of interphase?
A
The cell replicates its DNA.
B
The cell divides its cytoplasm.
C
The cell undergoes mitosis.
D
The cell grows and synthesizes proteins necessary for DNA replication.
Verified step by step guidance1
Understand that the G1 phase is part of the cell cycle, specifically the first phase of interphase, which occurs before DNA replication.
Recognize that during the G1 phase, the cell is primarily focused on growth. This involves increasing in size and producing the necessary organelles and cellular components.
Identify that protein synthesis is a key activity during the G1 phase. The cell synthesizes proteins and enzymes that are crucial for the next phase, S phase, where DNA replication occurs.
Acknowledge that the cell also monitors its environment and internal conditions to ensure it is ready for DNA replication. This includes checking for DNA damage and ensuring sufficient energy and resources are available.
Conclude that the G1 phase is essential for preparing the cell for DNA replication and subsequent cell division, ensuring that the cell is adequately equipped and healthy to proceed.
