Question

Which of the following stages marks the reverse effect of prophase and prometaphase?
(A)Metaphase
(B)Anaphase
(C)Both A and D
(D)Telophase

Answer 1

It is the last stage of the cell cycle. In cell biology, mitosis is a step of the cell cycle, in that the replicated chromosomes divide into two new nuclei. Cell division forms eventually to genetically similar cells in which the total number of chromosomes is used.

Complete answer:
During telophase, the impact of prophase and prometaphase is reversed. Two daughter nuclei are formed in individual daughter cell, and phosphatases dephosphorylate the nuclear lamellae at the distal part of the cell, forming nuclear envelopes surrounding the each nucleus

Additional information:
The final stage of mitosis, telophase, is in various ways the reverse of prophase. When the two sets of halved chromosomes have found their place, the spindle vanishes, and the nuclear membrane is eventually found around each new nucleus. In prophase, the nucleolus vanishes and chromosomes condense and become apparent. In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules found closed to kinetochores.... In telophase, chromosomes come at the opposite poles, and nuclear envelope substance around the single set of chromosomes.

Therefore, the correct answer is ‘Telophase’.

Note: In general, mitosis (a division of the nucleus) is followed by the S-stage of the interface (during which DNA replicates) and is mostly preceded by telophase and cytokinesis; that splits a cell's cytoplasm, organelles, and cell membrane into two new cells containing having approximately equal proportions of these cellular components. All the different stages of mitosis define the mitotic (M) phase of an animal cell cycle: the division of the stem cell into two daughter cells that are genetically identical to each other.
