|
|
|
DNA replicates during cytokinesis
|
|
|
Little happens during the G1 and G2 phases
|
|
|
Interphase consists of the G1, S, and G2 phases
|
|
|
The M phase is usually the longest phase
|
Detailed explanation-1: -Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents.
Detailed explanation-2: -During interphase, G1 involves cell growth and protein synthesis, the S phase involves DNA replication and the replication of the centrosome, and G2 involves further growth and protein synthesis.
Detailed explanation-3: -So, the correct statement is ‘G2 phase is pre-mitotic phase characterised by the formation of new proteins.
Detailed explanation-4: -So, the correct answer is ‘Cell is metabolically active, grows but does not replicate its DNA. ‘
