Question

Which is the resting but metabolically active stage of the cell cycle?

Hint:

The G0 phase is a type of quiescence where cells are metabolically active but not dividing. It is crucial for maintaining the function of differentiated cells.

Answer 1

Step 1: Define the Stages of the Cell Cycle.
The cell cycle consists of several stages: Interphase (G1, S, G2), and Mitotic phase (M phase, which includes mitosis and cytokinesis). During these stages, the cell grows, replicates its DNA, and divides.
Step 2: Focus on the Resting but Metabolically Active Stage.
The resting but metabolically active stage of the cell cycle is {Interphase}, particularly the G0 phase. In the G0 phase, cells are in a resting state, but they are still metabolically active. They perform essential functions, such as protein synthesis, maintaining cell structure, and other maintenance tasks, but they do not prepare for cell division.
Step 3: Importance of G0 Phase.
The G0 phase is typically observed in differentiated cells that have permanently exited the cell cycle, such as neurons and muscle cells. These cells are not actively dividing, but they still carry out the necessary functions required for survival.
