What is the primary purpose of the cell cycle?
A
To ensure accurate replication and division of a cell's genetic material
B
To transport molecules across the cell membrane
C

Verified step by step guidance1
Understand the cell cycle: The cell cycle is a series of events that cells go through as they grow and divide. It consists of interphase (growth and DNA replication) and mitotic phase (division). Its primary purpose is related to genetic material replication and division.
Analyze the options: Review each answer choice and determine which aligns with the primary function of the cell cycle. For example, transporting molecules across the cell membrane is a function of membrane proteins, not the cell cycle.
Focus on genetic material: The cell cycle ensures that the cell's DNA is accurately replicated during interphase and equally distributed to daughter cells during mitosis. This is critical for maintaining genetic integrity.
Eliminate unrelated options: Producing energy for cellular respiration and synthesizing proteins for cell structure are important cellular processes but are not the primary purpose of the cell cycle.
Select the correct answer: Based on the analysis, the correct answer is 'To ensure accurate replication and division of a cell's genetic material,' as this is the central role of the cell cycle.
