Explanation / Answer

Q3.

DNA synthesis - S phase

Synthesis of protein for cell division - G2

Normal cell activities - G0

Check accuracy - G2

Cell division - mitosis

G phases are gap phases. It acts as a check point before entering an active phase of cell cycle.

G0 is the resting phase where normal cell activities take place. This is not applicable for neurons.
G1 is before S phase and it checks whether required water and food are ready to enter S phase.
S phase is the synthesis phase where DNA replication begins.
G2 phase checks the DNA for errors and repair mechanism is initiated. Also, the protein required for M phase is synthesized.
M phase (mitosis) includes cytoplasmic (cytokinesis) and chromosome (karyokinesis) division.
