Question

What are the differences between interphase and interkinesis?

Answer 1

Hint: Before learning the differences, it is important for us to know about what is interphase and interkinesis.
Interphase is that phase of the cell cycle where the cell prepares itself for cell division. It is the phase when the cell is actually the most metabolically active. On the other hand, interkinesis is basically the phase between the 1st and 2nd meiotic division where the cell after completion of the 1st meiotic division waits for some time before entering the 2nd meiotic division.

Complete answer:
The major differences between interphase and interkinesis are:

INTERPHASE	INTERKINESIS
It is the phase that occurs before the starting of cell division.	It is the phase which is present in between the two meiotic division,
It occurs in case of both mitotic and meiosis cell division cycles.	It occurs only in meiotic division cycles.
This phase includes G1 phase, S phase, and G2 phases.	S phase is absent in interkinesis. It means that no DNA replication occurs during interkinesis.
The duration of interphase varies from cell to cell.	The interkinesis is of a short period of time generally. Sometimes the meiotic cells may also proceed to meiosis II directly after completion of meiosis I. In such cases, interkinesis is also absent although it is a bit rare.
Another G0 phase is also present and included in the interphase.	No such phase is present.

Note:
The fact that how long a cell will stay in the interphase or interkinesis is genetically controlled. Both these are the phases where a cell prepares itself for division. It gathers nutrients, synthesizes necessary proteins, replicates its DNA content (only in interphase). All these processes are guarded by certain ‘checkpoints’. If only all the processes occur normally, then the checkpoints allow the cell cycle to proceed.
Interphase and interkinesis are phases of high metabolic activity. The cell grows both in size and volume. A parameter called Nucleoplasmic Index (NPI) decides when the cell is ready to divide.
