Question
Cell cycle
Answers
GPT 3.5
The cell cycle is the series of events that occurs in a cell as it grows and divides into two daughter cells. It consists of four main phases:
1. G1 Phase (Gap 1): The cell grows and carries out its normal functions. It prepares for DNA replication.
2. S Phase (Synthesis): DNA replication occurs during this phase. The cell copies its DNA in preparation for cell division.
3. G2 Phase (Gap 2): The cell continues to grow and prepare for mitosis (cell division). It checks for any errors in DNA replication and repairs them if necessary.
4. M Phase (Mitosis): The cell divides into two daughter cells. This phase consists of several sub-phases including prophase, metaphase, anaphase, and telophase.
After mitosis, the daughter cells enter the G1 phase again and the cell cycle starts anew. The cell cycle is regulated by several checkpoints to ensure that the cell is ready for each phase and to prevent abnormal cell growth.
