Mitosis in Fungi
Mitosis is the process of cell division that occurs in eukaryotic cells. In fungi, mitosis is a complex process that involves several events. Let us discuss the events that occur during mitosis in fungi and identify the event that does not occur.
Segregation of Chromosomes
During mitosis in fungi, the chromosomes are replicated and segregated into two daughter cells. The segregation of chromosomes occurs in a highly regulated manner to ensure that each daughter cell receives an equal number of chromosomes.
Replication of the Genetic Material
Before mitosis, the genetic material in the cell is replicated to ensure that each daughter cell receives a complete set of chromosomes. Replication occurs during the S phase of the cell cycle.
Formation of Spindle Fibers
The spindle fibers are essential for the segregation of chromosomes during mitosis. The spindle fibers are microtubules that attach to the chromosomes and pull them apart during cell division.
Disintegration of Nuclear Envelope
During mitosis, the nuclear envelope disintegrates to allow the spindle fibers to access the chromosomes. This allows the chromosomes to be properly segregated into the daughter cells.
Conclusion
From the above discussion, it is clear that all the events mentioned (a, b, and c) occur during mitosis in fungi. The event that does not occur is the disintegration of the nuclear envelope. This event occurs in other eukaryotic cells, but not in fungi. Instead, fungi have a unique mechanism of mitosis that involves the formation of a spindle pole body.
