Question

Which best represents the role of the cell cycle in repair of an organism?

Answer 1

Answer:

The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to duplication of its DNA (DNA replication) and division of cytoplasm and organelles to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells.[1] In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into two main stages: interphase and the mitotic (M) phase (including mitosis and cytokinesis). During interphase, the cell grows, accumulating nutrients needed for mitosis, and undergoes DNA replication preparing it for cell division. During the mitotic phase, the replicated chromosomes and cytoplasm separate into two new daughter cells.

Explanation:

Another example of the Eukaryotic unicellular organism is “Amoeba.” An amoeba uses cell division for the production of new individuals. In the case of multicellular organisms, mitosis helps in growth and repair by producing more number of identical cells.

thanks for asking..

Answer 2

Mitosis process helps in the repair of an organism.

1. Mitosis plays the main role in developing and in growth of a multicellular animal or organism. For example - an egg that is fertilized gets developed into an embryo which then transforms into an adult by the process of mitosis.

2. By the process of mitosis, the old and the dead or worn out cells gets replaced by the new cells.

3. Mitosis process also heals wounds by producing new cells.
