Question

1. which of the following are key purposes of the cell cycle?

select two correct answers.
the cell cycle enables cells to move and interact with their environment.
the cell cycle allows organisms to produce energy.
the cell cycle replaces old or damaged cells.
the cell cycle ensures that daughter cells have identical genetic information as the parent cell.
the cell cycle controls the breakdown of waste within the cell.

Explanation:

The cell cycle is a series of events that take place in a cell leading to its division and duplication (replication) that produces two daughter cells. During the cell cycle, DNA replication occurs in the S - phase, and then in mitosis (M - phase), the replicated DNA is equally distributed to the daughter cells, ensuring that they have identical genetic information as the parent cell. Also, the cell cycle is involved in cell growth and division which is related to the production of new cells. While cells can produce energy through processes like cellular respiration (not directly the main purpose of the cell cycle), and cell movement and waste breakdown are functions of other cellular mechanisms rather than the key purposes of the cell cycle. Replacing old or damaged cells is more related to apoptosis and cell renewal mechanisms that are sometimes coordinated with the cell cycle but not the most fundamental purposes compared to genetic information transfer and cell division - related energy production (in the context of cell growth and division).

Answer:

The cell cycle allows organisms to produce energy.
The cell cycle ensures that daughter cells have identical genetic information as the parent cell.
