Question

What happens in interkinesis.
(a)DNA replication
(b)Chromosome replication
(c)Preparation of second meiotic division
(d)Resting stage

Answer 1

Hint: The time period in which a cell is at rest and slowly preparing itself for the next phase of division. The spindle fibers can split into two for the second division.

Complete answer:
Interkinesis is a word derived from inter means between and kinesis means movement or interphase II is a period of rest that occurs in the cells of some of the species that undergo during meiosis between meiosis I and meiosis II. It is the stage for the preparation of the cell before entering the second meiotic division. It does not occur in all organisms, where nuclear envelopes temporarily reform between meiosis I and II

Additional Information: -Interphase is the resting stage of the cell cycle where a cell mostly stays. During interphase, the cell prepares itself for mitosis and replicates the copies of its DNA.
-This phase was formerly called the resting phase. However, interphase is not the stage in which the cell simply rests in fact the cell is found to be living and preparing for the cell division.
-Meiosis is a special type of cell division in sexually-reproducing organisms used to produce gametes, such as sperm or egg cells.
-A common misconception is that interphase is the first stage of mitosis, but since mitosis is the division of the nucleus, prophase is the first stage.
-There are two divisions of meiosis (meiosis I and meiosis II), both of them have the same stages as that of the mitosis (prophase, metaphase, anaphase, telophase).
-Meiosis undergoes two rounds of division which will produce four cells with a haploid number of chromosomes.
-Meiosis occurs before the interphase. During this stage, the DNA is replicated which leads to the production of chromosomes which consists of two sister chromatids.
-Between the two divisions of meiosis I and meiosis II a second growth phase which is called interkinesis may occur. There will be no DNA replication in this stage.
-During interkinesis, in the second meiotic division, the spindle reassembles which were disassembled during the first meiotic division.
-Before prophase II, the cell of many plants undergoes Interkinesis which is followed by telophase I while certain plants skip both the stages and enter directly into the prophase II stage.

So, the correct answer is the ‘Preparation of second meiotic division’.

Note: Cell division is the process by which a parent cell divides into two or more daughter cells. In eukaryotes, there are two types of cell division: mitosis (megaspore mother cell divides to form two daughter cells), and meiosis (megaspore mother cell divides to form four daughter cells). It was first discovered by German botanist Hugo von Mohl in 1835 and was first filmed in 1943 by Kurt Michel.
