Question

What is the goal of a cell cycle?

Answer 1

Hint:
Cell cycles are the processes by which cells grow and divide. Cells spend most of their time in interphase, during which they grow, replicate their chromosomes, and prepare to divide. After leaving the interphase, the cell undergoes mitosis and divides. In the process, daughter cells enter their interphases and begin a new cycle of cell division.

Complete step by step answer:
There are four stages in the cell cycle: G1, S, G2, and M. During G1, the cell prepares to divide. Following this, the cell enters the S phase (S stands for the synthesis of DNA), where it copies all its DNA. When all the genetic material is copied and the cell has an extra set of DNA, it moves into G2, where it organizes and condenses the genetic material and prepares for division. During the next stage, M, the cell divides the DNA into two daughter cells and partitions the two copies into two daughter cells. Upon completion of the M phase, cell division occurs, leaving two cells, and the cycle can resume.

The main objectives are: The cell cycle maintains normal metabolic functions and assists in growth and development. It helps in gamete formation and reproduction. In addition to repairing and regenerating cells, it also maintains the cell's total chromosome count.

Additional Information:
Cell cycles are completed at different rates in different cells. The typical human cell divides every 24 hours, but mammalian cells that are fast-cycling, like those that line the intestine, can divide every 9-10 hours in culture.

Note:
Mitosis is a complex and highly regulated period of the cell cycle that lasts only a few minutes. During the course of events, phases are formed when one set of activities is completed and the next is started.
