CELL DIVISION

MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Scientists use this word to refer to a “pause” in between meiosis I and meiosis II. During this phase, centrosomes replicate but chromosomes do not.
A
Cytokinesis
B
Interkinesis
C
Interphase
Explanation: 

Detailed explanation-1: -The gap between meiosis I and meiosis II is known as interkinesis or interphase II which is also known as the rest phase and in this phase, there is no DNA replication.

Detailed explanation-2: -The stage between meiosis-I and meiosis-II is called interkinesis. During interkinesis, the proteins needed for meiosis-II replenish. Interkinesis is followed by prophase-II. In interphase, the cell undergoes preparations to divide and the DNA replication occurs during interphase.

Detailed explanation-3: -First thing to remember is that interphase is a stage associated with replication of DNA, and growth. Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. Hence between meiosis I and meiosis II, there is no interphase.
