G1 Phase
Multiple Choice
During the G1 phase of the cell cycle, which of the following is a major cellular event related to cell structures?
A
Synthesis of proteins and organelles (e.g., increased production of ribosomes and mitochondria) to support cell growth
B
Division of the cytoplasm to produce two daughter cells (cytokinesis)
C
Separation of sister chromatids and formation of two identical nuclei
D
Replication of nuclear DNA to form sister chromatids
Verified step by step guidance1
Understand the phases of the cell cycle: G1, S, G2, and M phases, each with distinct cellular events.
Recall that the G1 phase is primarily focused on cell growth and preparation for DNA replication, involving synthesis of proteins and organelles.
Recognize that cytokinesis (division of the cytoplasm) occurs after mitosis, not during G1.
Know that separation of sister chromatids and formation of two nuclei happen during mitosis, specifically in anaphase and telophase, not G1.
Remember that replication of nuclear DNA occurs during the S phase, which follows G1.
