Question

_________________ is the longest stage of meiotic division.
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase

Answer 1

Hint:-Cell cycle is a biological process, in which a single cell divides and produces daughter cells. Cell division is two of types, Mitotic cell division, and Meiosis cell division. The daughter cells of mitotic cell division are diploid while the daughter cells of meiosis cell division are haploid. But the mother cell in both divisions is diploid.

Complete step-by-step solution:-
 In mitotic cell division, a single mother cell divides into two daughter cells this type of cell division is found in somatic cells. It occurs in two phases, Interphase and M- phase, Interphase is a preparatory phase of cell cycle, in which cell prepares for division and, in M- phase cell divides. Interphase is further split into three phases, G1 phase, S- phase, and G2- phase and M- Phase is also further divided into four phases; prophase, metaphase, anaphase and telophase. Let’s find out the answer to the given question.
As we discuss, M – Phase, occurs in four sub-phases, let’s talk about the sub – phase one by one,
Prophase: It’s the first and longest phase of mitosis division, during this phase, chromosomes appear by condensation of chromosomes, and the nuclear envelope or nuclear membrane become disappears, and centrioles just near the nucleus begins to separate and move towards the opposite poles of the cells. Once the centrioles shift, they initiate the formation of mitotic spindle fibres.
Metaphase: During Metaphase, spindle fibres attach to centromere of sister chromatids, to separates the sister chromatids,
Anaphase: After metaphase, anaphase comes, in this phase chromatids separate and the centromeres divide, and each of sister chromatids move to each pole of the cell, and at the end of anaphase both pole has a complete set of chromosomes.
Telophase: In this phase, the spindle fibres disappear and at the end of the telophase, the cytoplasmic components begin to divide. Nuclear membranes or envelopes form around the both sides of chromosomes.
