The late prophase is one of the stages in mitosis and during this stage there is a break up of the nuclear envelope and the microtubules that the spindle fibers are made up of called the polar fibers reach from the pole to the equator of each cell. Specialized regions that are in the centromeres of chromosomes called Kinetochores attach to kinetochore fibers which are a type of microtubules. The spindle polar fibers connect the polar fibers to the kinetochores through their interaction with the kinetochore fibers and the chromosomes start to migrate towards the center of the cell.

During prophase in meiosis, homologous chromosomes pair up and undergo crossing over, exchanging genetic material. This process does not occur during mitosis, where individual chromosomes line up and separate without crossing over.
No, crossing over occurs during prophase 1 of meiosis, not prophase 2.
During prophase I of meiosis, homologous chromosomes pair up and undergo crossing over, where segments of DNA are exchanged between them. This does not occur during prophase of mitosis, where homologous chromosomes do not pair up or undergo crossing over.
During prophase of the cell cycle, the DNA condenses and coils tightly to form visible chromosomes. This process helps to organize and prepare the DNA for cell division.
During mitosis, chromosomes are in their most condensed form during metaphase
Prophase.

In late prophase, the nuclear envelope breaks down. This allows the chromosomes to be fully condensed and ready for division during metaphase.

The pairing up of maternal and paternal chromosomes during meiosis happens in the prophase I stage. This pairing is called synapsis and results in the formation of a structure called a tetrad.
The synaptonemal complex disappears during the diplotene stage of meiosis. This dissolution marks the end of the physical connection between homologous chromosomes, allowing them to separate and continue with the process of meiosis.

Crossing over occurs during Prophase I of meiosis.
No, crossing over occurs during prophase 1 of meiosis, not prophase 2.
