In the overview of the eukaryotic cell cycle, interphase typically lasts for what fraction of a cell's life?
A
About 50% of the cell’s life
B
About 90% (most) of the cell’s life
C
About 100% of the cell’s life
D
About 10% of the cell’s life
Verified step by step guidance1
Understand that the eukaryotic cell cycle consists of two main phases: interphase and mitotic phase (M phase). Interphase includes G1, S, and G2 phases, where the cell grows and DNA is replicated.
Recall that interphase is the longest part of the cell cycle, during which the cell prepares for division by growing and duplicating its DNA.
Recognize that the mitotic phase, where actual cell division occurs, is relatively short compared to interphase.
Based on typical cell cycle timing, interphase usually occupies the majority of the cell's life, often around 90%, while mitosis and cytokinesis take up the remaining time.
Therefore, the fraction of a cell's life spent in interphase is approximately 90%, which is the correct answer among the given options.
