S phase

G2
|
Detailed explanation-1: -The G1 phase stands for gap 1 and is when organelles replicate and the cell grows. The S phase stands for synthesis and is when DNA is replicated.
Detailed explanation-2: -During the cell cycle, RNA and protein synthesis takes place during the G1 and G2 phases. The cell cycle is an ordered set of events, culminating in cell growth and division into two daughter cells.
Detailed explanation-3: -In G1, cells accomplish most of their growth; they get bigger in size and make proteins and organelles needed for normal functions of DNA synthesis. Here, proteins and RNAs are synthesized, and, more especially the centromere and the other components of the centrosomes are made.
Detailed explanation-4: -During G1 phase, the cell grows in size and synthesizes mRNA and proteins (Known as histones) that are required for DNA synthesis. Once the required proteins and growth are complete, the cell enters the next phase of the cell cycle, S phase.
