G1 Phase
Multiple Choice
During the G1 phase of the eukaryotic cell cycle, which of the following events primarily occurs?
A
Duplication of the cell's DNA to form sister chromatids
B
Separation of sister chromatids and division of the nucleus
C
Cell growth with active RNA and protein synthesis, preparing for DNA replication
D
Formation of the mitotic spindle and alignment of chromosomes at the metaphase plate
Verified step by step guidance1
Understand the phases of the eukaryotic cell cycle: G1, S, G2, and M phases.
Recall that the G1 phase is the first gap phase after cell division, where the cell grows and carries out normal metabolic activities.
Recognize that during G1, the cell actively synthesizes RNA and proteins to prepare for DNA replication, but DNA duplication itself occurs in the S phase.
Note that duplication of DNA to form sister chromatids happens in the S phase, not G1.
Remember that mitotic spindle formation and chromosome alignment occur later during mitosis (M phase), and separation of sister chromatids happens during anaphase of mitosis.
