Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The cell cycle is the ____
A
time from prophase until cytokinesis.
B
period of time between the birth and the death of a cell.
C
time it takes for one cell to undergo mitosis.
D
series of events that cells go through as they grow and divide.
Explanation: 

Detailed explanation-1: -A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Detailed explanation-2: -The Cell Cycle. The cell cycle is a series of events that cells go through as they grow and divide. During the cell cycle, a cell grows, prepares for division, and divides to form two daughter cells, each of which then begins the cycle again. The Cell Cycle is broken down into 4 distinct phases: G1, S, G2, and M phase.

Detailed explanation-3: -During the mitotic (M) phase, the cell divides its copied DNA and cytoplasm to make two new cells.

Detailed explanation-4: -The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material. The cell cycle is complete when each daughter cell is surrounded by its own outer membrane.

Detailed explanation-5: -The mitotic phase is a multistep process during which the duplicated chromosomes are aligned, separated, and moved to opposite poles of the cell, and then the cell is divided into two new identical daughter cells.
