NEET BIOLOGY

Detailed explanation-1: -The interphase is the period when the cell is in a non-dividing state and this can be in different stages: the first gap (G1) between the last mitosis and the S phase (phase of DNA synthesis) and the second gap (G2) between the completion of the S phase and the next mitosis (M).

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: -G1 phase (Gap 1)-Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis)-Each of the 46 chromosomes are duplicated by the cell. III. G2 phase (Gap 2)-The Cell “double checks” the duplicated chromosomes for error, making any needed repair.

Detailed explanation-4: -Prophase which is the first stage of mitosis follows the S and G2 phases of interphase.

Detailed explanation-5: -Stages of the cell cycle 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.
