Question

Explain in one sentence
(i) Interphase ..................................................................................................
(ii) Synthetic-phase .........................................................................................
(iii) Dividing-phase ..........................................................................................

Answer 1

Answer:

1. the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.

2. S phase (Synthesis Phase) is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved.

3. M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm divides forming two daughter cells. ... Cells that have temporarily or reversibly stopped dividing are said to have entered a state of quiescence called G0 phase.

Answer 2

The explaination of the asked phases are provided here -

(i) Interphase

It is the phase where the cell starts growing. It means that the cell starts preparing itself to undergo division.

In this phase, no any kind of activity regarding the division of cell occurs and due to this, this phase is also known as the phase of rest.

(ii) Synthetic phase

Here the DNA gets replicated. Also here during replication, the DNA amount becomes double while the quanity of chromosomes stays the same.

(iii) Dividing phase

This phase is the most active one as the cell division process takes place here.
