What is the S phase of the cell cycle, and what occurs during this phase?
A
The S phase is when the cell undergoes cytokinesis.
B
The S phase is when the cell synthesizes proteins for cell division.
C
The S phase is when the cell replicates its DNA.
D
The S phase is when the cell grows and performs normal functions.
Verified step by step guidance1
Understand the cell cycle: The cell cycle is a series of phases that cells go through to grow and divide. It consists of interphase (G1, S, and G2 phases) and the mitotic phase (M phase).
Identify the S phase: The S phase, or synthesis phase, is part of interphase. It follows the G1 phase and precedes the G2 phase.
Learn what occurs during the S phase: During the S phase, the cell replicates its DNA. This is crucial for ensuring that each daughter cell receives an identical set of chromosomes during cell division.
Differentiate the S phase from other phases: Unlike the G1 phase, where the cell grows and performs normal functions, or the G2 phase, where the cell prepares for mitosis, the S phase is specifically dedicated to DNA replication.
Clarify misconceptions: The S phase is not involved in cytokinesis (which occurs during the M phase) or protein synthesis for cell division (which primarily occurs during the G2 phase).
