M- phasein motosis undergoes which type of division?a)Cytokinesisb)Diakinesisc) Reductional divisiond)Equational divisionCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

According to question which is 'M phase undergoes' why the answer could not be reductional division

Answer

Since, in mitosis the number of chromosomes in the parent and progeny cells is the same, it is also called as equational division.

Answer

M-phase in mitosis undergoes equational division.

Mitosis is a type of cell division that occurs in eukaryotic cells and is responsible for the distribution of replicated chromosomes to two daughter cells. The process of mitosis consists of several stages, including interphase, prophase, metaphase, anaphase, and telophase. The M-phase refers to the phase where the actual division of the cell takes place.

Equational division, also known as mitotic division, is the type of division that occurs during the M-phase of mitosis. It is called equational division because it results in the equal distribution of genetic material to the daughter cells, ensuring that they receive the same number and type of chromosomes as the parent cell.

During equational division, the replicated chromosomes align at the center of the cell during metaphase. The spindle fibers, which originate from opposite poles of the cell, attach to the centromeres of each chromosome. This alignment ensures that each daughter cell will receive an equal number of chromosomes during cell division.

Once the chromosomes are properly aligned, anaphase begins. In anaphase, the spindle fibers shorten and pull the sister chromatids apart, separating them into individual chromosomes. These chromosomes are then pulled towards the opposite poles of the cell, ensuring that each daughter cell will receive a complete set of chromosomes.

Finally, in telophase, the two sets of chromosomes reach the opposite poles of the cell, and the nuclear envelope reforms around each set. This is followed by cytokinesis, the process of dividing the cytoplasm and organelles between the two daughter cells.

In summary, during the M-phase of mitosis, equational division occurs, resulting in the equal distribution of genetic material to the daughter cells. This ensures that each daughter cell receives the same number and type of chromosomes as the parent cell.

Answer

Answer is c and d both because m phage divided into mitosis and meiosis

Answer

Always M phase stands for mitosis?it can be meiosis also

Answer

M-phase includes both Equational (mitosis) division and Reductional (meiosis) division so the answer would include both c) and d)

Answer

D
