Detailed explanation-1: -The cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produce two genetically identical cells.

Detailed explanation-2: -The series of events that occurs from when a cell forms until it divides into two daughter cells is called the cell cycle. Every cell cycle includes four main events: 1) reception of a signal to divide, 2) DNA replication, 3) segregation of the replicated DNA, and 4) division of the cytoplasm.

Detailed explanation-3: -The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).

Detailed explanation-4: -In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.

Detailed explanation-5: -The cell cycle is the orderly sequence of events in which a cell duplicates its contents and divides into two new cells. The first part of the cycle is preparation for mitosis: the cell grows, accumulates nutrients, and, most importantly, copies all its chromosomes, so that there are two identical sets of DNA.
