G2 Phase

Detailed explanation-1: -So the correct answer is the ‘G1 phase’.
Detailed explanation-2: -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-3: -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. The G2 phase stands for gap 2 and is when DNA is proofread and DNA damage is repaired.
Detailed explanation-4: -Interphase. Interphase consists of three steps: G 1start subscript, 1, end subscript phase: first gap phase; the cell grows larger and organelles are copied. S phase: synthesis phase; the cell synthesizes a complete copy of the DNA in its nucleus.
