Question

What are "cell formation cycles" and why would one want to use them?

Answer 1

The cell cycle is the series of events that take place in a cell, which leads to its division and duplication of its DNA also known as DNA replication to produce two daughter cells, in prokaryotes which lack a nucleus, the cell cycle is divided into the BCD periods. The B period extends from the end of the cell division to the beginning of DNA replication. DNA replication occurs during the C period and the D period refers to the stage between the end of replication and the splitting of the bacterial cell into two daughter cells.

why would we want to study them - Thee cell division cycle is a vital process by which a single celled fertilised egg develops into the mature organism also the process also controls by which hairs, skin, blood cells and most of the internal organs are renewed.

After cell division, each of the daughter cells begin the interphase of the new cycle, each phase of the cell cycle is a distinct set of specialized biochemical process that prepare the cell for initiation of the cell divisions. There are following points in a cycle:

1. Phases
2. Regulation of cell cycle
3. Check points

Cell cycle monitors the cells by Check points and regulated the process of cell cycle through various phases. This allows the verification and repairing of DNA damage. Cell cannot proceed to the next phase till the checkpoint is not verified and requirements have not been met. These checkpoints are usually regulatory proteins. Some check points in different phases are:

1. G1/S
2. G2/M
3. Metaphase (mitotic)
