Multiple Choice
Which of the following occurs during the G2 stage of interphase?
A
Separation of sister chromatids
B
Cell growth and preparation for mitosis
C
Chromosome condensation
D
DNA replication
Verified step by step guidance
1
Understand the cell cycle: The cell cycle consists of interphase and mitotic phase. Interphase is further divided into G1, S, and G2 phases.
Identify the G2 phase: The G2 phase is the final part of interphase, following DNA replication in the S phase.
Recognize the activities in G2 phase: During the G2 phase, the cell continues to grow and prepares for mitosis. This includes synthesizing proteins and organelles necessary for cell division.
Differentiate between the options: Separation of sister chromatids occurs during mitosis, specifically in anaphase. Chromosome condensation begins in prophase of mitosis. DNA replication occurs in the S phase, not G2.
Conclude the correct activity: The G2 phase is characterized by cell growth and preparation for mitosis, making this the correct answer.
