Prophase
How many stages does Prophase have?
5 (five)
When does prometaphase occur?
(Between prophase and metaphase, Between anaphase and telophase, Between telophase and anaphase, or Between metaphase and anaphase)
Between prophase and metaphase
Which stage is metaphase?
Metaphase is the third phase of mitosis.
True or False: The nucleous begin to form in Anaphase
False
How long does telophase last?
3 to 12 minutes
Prophase occurs in____?
(Mitosis, Meiosis, Both, or Neither)
Both
When does prometaphase begin?
In metaphase, the _____ are lined up at the center of the dividing cell. (Centrosomes, Microtubules, Chromosomes, Centromeres)
Chromosomes
During anaphase ____.
Disjunction occurs, spindle fibers shorten, the cell elongates, All of these occur, None of these occur.
All of these occur
How many chromosomes are in telophase?
23
How does prophase start?
The cell starts to break down some structures and build others up, setting the stage for division of the chromosomes.
What breaks down in prometaphase?
The nuclear envelope
Why does metaphase need to happen?
The cell ensures that it is ready to divide.
What happens in anaphase?
The sister chromatids separate from each other and are pulled towards opposite ends of the cell.
What happens during telophase in mitosis?
The cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.
What are the stages of prophase?
Lepotene, Zygotene, Pachytene, Diplotene, and Diakinesis.
Where does prometaphase take place?
Within the nuclear membrane in closed mitosis, or outside the nuclear region as In open mitosis.
Spindle fibers attach to the centromere of each pair of sister chromatids
Why is anaphase important?
What would happen without telophase?
What are the key events of prophase?
Chromatin condenses, Nucledi disappear, Duplicated chromosomes appear as sister chromatids, Mitotic spindle begins to form, Centrosomes move away from each other.
What happens to DNA during prometaphase?
The nuclear membrane disintegrates and the mitotic spindle gains access to the chromosomes.
What are three things that happen during metaphase?
What happens if anaphase goes wrong?
What occurs during telophase that signifies the end of mitosis?
Cytokinesis usually begins during late anaphase and is almost complete by the end of telophase, resulting in the formation of two interphase daughter cells.
