Mitosis Flashcards
what happens in mitosis?
a parent cell divides into two daughter cells
In what phase is DNA replicated?
Interphase (S)
What do chromatids condense into?
Chromosomes
Why do chromatids condense?
To make DNA easier to move and prevent mutations
Why is DNA usually kept as chromatin?
So it can be read, duplicated, and used
What is the mitotic spindle made of?
Microtubules and centrosomes
True or False: In prophase, centrosomes are pulled together.
False, they are pushed apart
In prometaphase, the nucleus
breaks apart
Where do chromosomes line up during metaphase?
The middle of the cell (metaphase plate)
During what phase are sister chromatids seperated?
Anaphase
What enzyme pulls sister chromatids apart during anaphase?
The enzyme seperase
Two new nuclei are formed during
telophase
During cytokinesis,
the cytoplasm divides
