Detailed explanation-1: -Interphase is divided into the first growth (G1), Synthesis (S), and the second growth (G2) phases (figure 1).
Detailed explanation-2: -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.
Detailed explanation-3: -The first part of interphase is called the first gap phase (G1). Cell growth marks the G1 phase of the cell cycle.
Detailed explanation-4: -The G1 stage stands for “GAP 1". The S stage stands for “Synthesis". This is the stage when DNA replication occurs. The G2 stage stands for “GAP 2". The M stage stands for “mitosis", and is when nuclear (chromosomes separate) and cytoplasmic (cytokinesis) division occur.
