1 \({G_1}\) Phase corresponds to interval between mitosis and initiation of DNA replication
2 During \({G_1}\) Phase the cell is metabolically active
3 DNA replication takes place during S-phase
4 Cell growth in terms of cytoplasmic increase is a discontinuous process
Explanation:
Although cell growth (in terms of cytoplasmic increase) is a continuous process, DNA synthesis occurs only during one specific stage in the cell cycle i.e. S-phase. \({G_1}\) phase corresponds to the interval between mitosis and initiation of DNA replication. During \({G_1}\) phase the cell is metabolically active and continuously grows but does not replicate its DNA.

During cell cycle, when does the following takes place respectively :- A. RNA and protein synthesis for cell growth B. RNA and protein synthesis for cell division
1 \({G_1}\) and \({G_2}\) - phase
2 S - phase and \({G_2}\) - phase
3 M - phase and \({G_2}\) - phase
4 \({G_1}\) and M - phase
Explanation:
During \({G_1}\) phase, the cell is metabolically active and synthesises RNA and protein that help with cell growth. During the \({G_2}\) phase, RNA and proteins are synthesised in preparation for mitosis while cell growth continues.

Which phase of cell cycle is known as quiescent stage?
1 M phase
2 \(\mathrm{G}_{0}\) phase
3 G phase
4 S phase
Explanation:
\(\mathrm{G}_{0}\) phase is non-cycling quiescent stage of cell which leaves the cell cycle in the early half of \({{\rm{G}}_{\rm{1}}}\) phase due to absence of cycling factors.

In a mitotic cell cycle if the initial DNA content in \(\mathrm{G}_{1}\) phase is \(10 \mathrm{pg}\) then the amount DNA in the resulting daughter cell is
1 20 pg
2 10 pg
3 30 pg
4 40 pg
Explanation:
The DNA content remains the same in mitosis, so the amount of DNA in the resulting daughter cell is also \(10 \mathrm{pg}\), which is the same as in the G1 phase.
