Question

what is the “cell cycle”?
a. a protein that recycles old cells
b. the division of a cell
c. the life cycle of a cell

Explanation:

The cell cycle refers to the series of events that take place in a cell leading to its division and duplication (replication) that produces two daughter cells. It encompasses the entire life cycle of a cell from its formation until it divides into new cells. Option a is incorrect as it refers to a protein function (not the cell cycle concept). Option b only focuses on cell division (a part of the cell cycle but not the whole). Option c correctly defines the cell cycle as the life cycle of a cell.

Answer:

C. The life cycle of a cell
