The chromatid threads begin to twist and condense, creating chromosomal structures which are visible to the microscope. Each chromosome then seeks out its homologous chromosome. After the homologous chromosomes pair, the structure is referred to as a tetrad. The point at which two non-sister chromatids intertwine is known as a chiasma. Sometimes a process known as crossing over occurs at this point.

How many cells are in prophase 2?

There are two cells in prophase II.


The events of prophase seem to be opposite of those that occur during what phase?

The events of prophase in mitosis, such as condensation of chromosomes and breakdown of the nuclear envelope, are opposite to those that occur during telophase, where chromosomes decondense, and the nuclear envelope reforms.


What appears in prophase 1?

In prophase I of meiosis, chromosomes condense, homologous chromosomes come together and may exchange genetic material through crossing over, and the nuclear membrane breaks down. These events are important for genetic recombination and the formation of genetically diverse gametes.

What is the phase that two new nuclear envelopes form?

The phase where two new nuclear envelopes form around the two sets of daughter chromosomes is called telophase. In telophase, the nuclear membrane reforms around the chromosomes and the nucleoli reappear. This marks the end of nuclear division in cell mitosis.


Which answer shows the correct series of events in the cycle?

Interphase, prophase, metaphase, anaphase, telophase, cytokinesis


What does pmat for mitosis mean?

"PMAT" is an acronym that represents the different stages of mitosis: Prophase, Metaphase, Anaphase, and Telophase. These stages describe the series of events that occur as a cell divides and the chromosomes are separated into two new daughter cells.


What organelles in prophase are important to the part of cell division?

centrioles


What stage mitosis is it when chromosomes shorten and thicken and the nuclear membrane begins to disappear?

The stage of mitosis where chromosomes shorten and thicken and the nuclear membrane begins to disappear is prophase. During prophase, the chromatin condenses into distinct chromosomes and the nuclear envelope breaks down, allowing the chromosomes to interact with the spindle fibers.


What important changes occur to the chromosomes and the nucleus of prophase of mitosis?

How is telophase the reversal of prophase?

Telophase and prophase are two distinct stages of mitosis. Telophase involves the separation of sister chromatids to opposite poles of the cell and the formation of new nuclear envelopes around the separated chromosomes. This is different from prophase, which involves the condensation of chromosomes, breakdown of the nuclear membrane, and formation of the mitotic spindle. In telophase, the events aim to reverse the processes that occurred in prophase to prepare for cell division.
