NEET BIOLOGY

Detailed explanation-1: -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".

Detailed explanation-2: -G1 phase. Interphase begins with G1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. S phase. During S phase, which follows G1 phase, all of the chromosomes are replicated.

Detailed explanation-3: -Although it would make sense for the G in G1 to stand for growth, it actually stands for gap. At the end of G1, the cell stops at a checkpoint. This checkpoint ensures that the cell has produced all of the necessary proteins, the cell is big enough, and the DNA is intact.

Detailed explanation-4: -The interphase is divided into three phases:-G1 phase (Gap 1) – G1 phase is the phase of the cell between mitosis and initiation of replication of the genetic material of the cell. During this phase, the cell is metabolically active and continues to grow without replicating its DNA.

Detailed explanation-5: -Introduction to the Cell Cycle Interphase has three sections. The G1 (first gap) phase is the interval between mitosis and the onset of DNA replication. The S (synthetic) phase is the time when DNA is replicated.
