Detailed explanation-1: -Cells in either mitosis or cell division (also called cytokinesis) are in the M phase, whereas those in the other three phases (G1, S, and G2) are in the interphase.

Detailed explanation-2: -After the mitosis phase, the cell enters the G1 phase. Upon entry, the DNA pre-replication complexes position themselves at origins preparing for DNA replication at S phase.

Detailed explanation-3: -Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

Detailed explanation-4: -The G1 phase, gap 1 phase, or growth 1 phase, is the first of four phases of the cell cycle that takes place in eukaryotic cell division. In this part of interphase, the cell synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis.
