Question

How is Interphase II of meiosis different from Interphase of mitosis and Interphase I o meiosis?

Answer 1

Hint: Interface is one of the longest stages of cell division in eukaryotic cells. During interphase, the cell restores all the nutrients that it requires for division and synthesizes proteins, and replicates DNA to start and initiate cell division.

Complete answer:
The Interface Stage is divided into three distinct sub stages- The ${G_1}$ phase, S phase, and the ${G_2}$ phase. There is an additional ${G_0}$ phase as well where the cells go and rest this is therefore known as the resting stage. The cells such as neurons that do not undergo cell division go into the ${G_0}$ phase and rest completely for the lifetime.
In the ${G_1}$ phase the cells replicate and grow in size they replicate their proteins and necessary nutrients which are required for cell division are produced.
After doing this the cells go to the G$0$ phase, which does not want to enter the cycle of cell division but those cells which are actively dividing continue to move from the ${G_1}$ phase to the S phase.
In the synthesis phase, the cell pauses its normal functioning and synthesizes all the proteins and the replication of DNA as well.
After the S- phase comes to the ${G_2}$ phase where all the replication is completed and the cell grows in size and adds volume to the cytoplasm.
After completion of the ${G_2}$ phase, the cells enter the division phase which is either mitosis or meiosis.
The division to form somatic cells is known as mitosis and the division to form gamete cells or the germ cells is known as meiosis.
The interphase stage of both mitosis and meiosis initiation is the same but since meiosis has two parts to it the interphase $2$ stage of meiosis is slightly different from the interface $1$ stage of meiosis.
Meiosis -I occurs after Interphase I, where proteins are grown in the G phase and chromosomes are replicated in the S phase.
Meiosis-II may begin with interkinesis or interphase II. This differs from interphase I because no S phase occurs, as the DNA has already been replicated. Thus only a G phase occurs.

Note: Mitosis is known as equational division whereas Meiosis-I is known as reductive division, as the cells are reduced from being diploid cells to being haploid cells. Meiosis II is also called equational division, as the cells begin as haploid cells and end as haploid cells. There are again four phases in meiosis II and these differ slightly from those in meiosis I.
