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.


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.


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 events in telophase are the opposite of prophase?

During telophase, the events that occur are essentially the reverse of those in prophase. The chromosomes, which condensed and became visible during prophase, de-condense back into chromatin. The nuclear envelope reforms around each set of separated chromosomes, restoring the nucleus. Additionally, the spindle fibers disassemble, contrasting with their formation during prophase.


What are the two distinct division of meiosis?

Meiosis I & Meiosis II


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.


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.


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

Interphase, prophase, metaphase, anaphase, telophase, cytokinesis


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