Question

When nutrients are suboptimal for cell growth and division, the cell cycle arrests. at which stage of the cell cycle/checkpoint would you predict this arrest to occur?

Answer 1

At what stage of late G1 phase (Gaps 1 phase) or at which cell cycle/checkpoint 'START' would you expect this arrest to occur.

What is Cell Cycle?

The cell cycle is the most basic function of the cell in the form of accurate duplication of large amounts of deoxyribonucleic acid in the chromosomes, which then separates the results of the duplication to form two new, identical cells.

Phases that Occur in the Cell Cycle

• S Phase (Synthesis): This phase is the stage of DNA replication. In general, human body cells need about eight hours to complete this stage.
• M phase (Mitosis): The time interval of M phase is approximately one hour. This stage occurs cell division, either binary fission or bud formation.
• G phase (Gap): G phase which consists of G1 and G2 is the phase of synthesis of substances needed in the next phase. In mammalian cells, the G2 phase interval is about 2 hours, whereas the G1 phase interval varies widely from six hours to several days. Cells that have been in the G1 phase for too long are said to be in the G0 or “quiescent” phase.
• Interphase: Interphase is a long pause between one mitosis and another. The break includes the G1, S, and G2 phases.
