Detailed explanation-1: -There are three stages of interphase: G1 (first gap), S (synthesis of new DNA ), and G2 (second gap). Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied. The cell grows and carries out biochemical functions, such as protein synthesis, in the G1 phase.

Detailed explanation-2: -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-3: -This is one of two ‘gap’ phases in the standard eukaryotic mitotic cell cycle. It is the interval between the completion of DNA synthesis and the beginning of mitosis. Protein synthesis occurs in this phase, following DNA replication in the S phase.

Detailed explanation-4: -G2 phase is the final phase of interphase, in which the cell synthesises a variety of proteins. Microtubules, a vital protein in mitosis, is also synthesised. G2 is also the final growth before M phase, a checkpoint of sorts to ensure intracellular components have been properly replicated.

Detailed explanation-5: -Cell cycle is the name we give the process through which cells replicate and make two new cells. Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.
