The duplication of the genetic content in a cell occurs during what part of interphase?

		a.Mitosis
		b.G1 phase
		c. S phase
		d. G2 phase

Expert Solution

The whole cell cycle process is mainly divided in phase - interphase and mitotic phase or M phase. In the interphase a cell prepare itself to undergo division. In the mitotic or M phase a mature cell actually divide and form two daughter cells. The whole interphase is further divided in 3 phases - G1 phase, S phase and G2 pahse. A newly formed cell first enters into the G1 stage. In this stage it acquire more cytoplasm and grow in size. In this phase italso synthesis the required proteins or enzymes for DNA replication. Sometimes a newly formed cell also can enter into G0 stage. This phase is called as resting phase. If a cell enters into this phase, it does not undergo further division at that time, may be it can enter into cell cycle later. After completion of G1 phase a cell enter into S phase. S is stands for synthesis. So in this phase the whole genetic material is synthesized. So the content of genetic material of that cell get duplicated. In other words we can say that the genetic content of the cell get doubled. After that cell enters into G2 pahse where the cell grow more in size and prepare all the enzymes and proteins require for the to undergo actually division process or enter into M phase.

So the correct option is C.In the S phase of interphase the genetic content of a cell undergo duplication.

Part A. During interphase, chromosomes look a bit different than they do during mitosis. Why is that? What happens during S-phase of the cell cycle and What happens during the G2 phase of the cell cycle to prepare a cell for mitosis. After reviewing, how many chromosomes are present in this cell during G2?
