During which phases of cell cycle, amount of DNA in a cell remains at 4C level if the initial is denoted as 2C?
1 \({G_0}\) and \({G_1}\)
2 \({G_1}\) and S
3 Only \({G_2}\)
4 \({G_2}\) and M
Explanation:
After DNA replication in S-phase, 2C DNA present in \({G_1}\) phase becomes 4C DNA in \({G_2}\) phase. A cell with 2C DNA in \({G_1}\) phase will now have 4C DNA. \({G_2}\) phase is second growth phase where DNA content either regains 2C level (mitosis) or becomes halved i.e., 1C (in meiosis). \({G_0}\) phase is the phase of differentiation where cell contains DNA which is same to its parent cell and does not divide further.

Assertion : Interphase is divisible into 3 stages \({G_1}\), S and \({G_2}\) phases. Reason : S-phase is also called invisible M-phase.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
Interphase has three stages \({G_1}\), S and \({G_2}\). S - Phase is also called invisible phase of M- phase since it is in this phase that the chromosomes prepare themselves for equitable distribution later on. During the S-phase, the genetic material of every chromosome is replicated.

Which of the following is correct about interphase?
1 It includes \({G_1}\), S, \({G_2}\)
2 It lasts for more than 95 per cent in the duration of cell cycle in human cell.
3 It is also known as resting phase.
4 All the above
Explanation:
Interphase represents the phase between two successive M phases. The interphase, though called the resting phase, is the time during which the cell is preparing for division by undergoing both cell growth and DNA replication in an orderly manner. The interphase lasts more than 95% of the duration of cell cycle. It is subdivided into – \({G_1}\), S and \({G_2}\) phases.
