The correct sequence of adult cell cycle phases is _______________ .
Understanding Cell Cycle Phases Sequence
The cell cycle is an ordered series of events leading to cell growth and division into two daughter cells. The typical sequence for actively dividing adult cells involves distinct phases.
Phases of the Cell Cycle
The main phases of the cell cycle occur in the following order:
- G1 Phase (Gap 1): Cell growth and normal metabolic activity occur. Proteins and organelles are synthesized.
- S Phase (Synthesis): DNA replication takes place, resulting in duplicated chromosomes.
- G2 Phase (Gap 2): Further cell growth and preparation for mitosis occur. Proteins necessary for division are synthesized.
- M Phase (Mitosis): The cell nucleus divides (mitosis), followed by division of the cytoplasm (cytokinesis), resulting in two daughter cells.
Determining the Correct Sequence
Based on the functions of each phase, the correct chronological order is G1, followed by S, then G2, and finally M.
Therefore, the correct sequence of adult cell cycle phases is G1-S-G2-M.
This corresponds to Option B.
