During this phase of cell division, the nuclear membrane dissolves, the chromatin coils

During this phase of cell division, the nuclear membrane dissolves, the chromatin coils, and centrioles begin to move to the poles of the cell.

a. prophase

b. metaphase

c. telophase

d. anaphase

Answer: a. prophase

For the cell division whether it is Mitosis or Meiosis, there are known series of stages and the process described in the question falls under one of them known as the Prophase. Prophase: At this stage, it is observed that the nuclear membrane starts to disintegrates; the chromosomes or chromatin fibres are distinguishable and appear more condensed. Also, the centrioles which are structures that aid in directing the formation of the microtubules of the spindle start to be transported to two poles of a cell. Consequently, before each phase of the cell cycle begins, several changes take place in the cell as it prepares for the subsequent processes of cell division or the division of the chromosomes and the distribution of the chromosomes into two new daughter cells. Further, the other phases like metaphase, anaphase, and telophase are basically prophase. They are found to be involved in chromosomal divisions along with nucleus modelling.
