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.

What cellular events occur during early prophase?
The chromatin condenses into thick thread-like structures that later become chromatids.
What events occur during prophase?
The nucleoli disappears; the nuclear membrane breaks down; the mitotic spindle appears and the centrioles begin moving towards opposite ends of the cell.
How can prophase and telophase be considered opposites?
Prophase is when chromosomes group together and prepare for division, while in telophase two new nuclei are formed. telophase is the first step of mitosis; telophase is the fourth step (last).
Name the phase of cell division when duplicated chromosomes first appear?
Duplicated chromosomes first become visible during prophase.
How many chromosomes are shown in prophase?
23 pairs
What is the phase that two new nuclear envelopes form?
In the Prophase. Nuclear envelope and nucleolus disappears.
What stage mitosis is it when chromosomes shorten and thicken and the nuclear membrane begins to disappear?
In prophase stage, the replicated chromosomes condense and the nuclear envelope disappears. Earlier in prophase, chromatin visible condenses into the chromosomes.
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.
The female is born with about two million halted at prophase?
halted at prophase I
How many cells are in prophase 2?
There are two cells in prophase II.
The most important occurrence during prophase one of meiosis which doesnt occur in prophase of mitosis is?
Crossing over, also known as genetic recombination, is a unique event that occurs during prophase I of meiosis but not during prophase of mitosis. It involves the exchange of genetic material between homologous chromosomes, resulting in genetic diversity among offspring.
What are the two distinct division of meiosis?
Meiosis I & Meiosis II
What the difference between prophase one and prophase two?
cheese is the difference between this question.
Number of cells during prophase?
There is still only 1 cell during prophase.
In meiosis 1 what events occurs of interphase?
There is only one interphase, and it's the same as other cells: to grow, function, and replicate DNA. Meiosis is only a small part of cell cycle and interphase is not included in it. There are, however, two different phases in meiosis, such as prophase I and prophase II.
Which answer shows the correct series of events in the cycle?
Interphase, prophase, metaphase, anaphase, telophase, cytokinesis
What organelles in prophase are important to the part of cell division?
centrioles
