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: -During the mitotic (M) phase, the cell divides its copied DNA and cytoplasm to make two new cells. M phase involves two distinct division-related processes: mitosis and cytokinesis.
Detailed explanation-3: -At the molecular level, however, interphase is the time during which both cell growth and DNA replication occur in an orderly manner in preparation for cell division. The cell grows at a steady rate throughout interphase, with most dividing cells doubling in size between one mitosis and the next.
Detailed explanation-4: -Mitosis is conventionally divided into five stages known as prophase, prometaphase, metaphase, anaphase, and telophase.
Detailed explanation-5: -In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases-G1 and G2, the so-called gap phases-are less dramatic but equally important.
