Flashcards in 4A -Mitosis and the Cell Cycle Deck (10):
What is the stage that must happen before mitosis can begin?
What is longer the interphase or mitosis?
What happens in the interphase?
1.Cell grows and organelles are replicated
2.DNA is copied and identical sister chromatids are formed
How is DNA found during the interphase?
What is the first stage of mitosis and what happens
1.Centrioles duplicate and move to opposite poles
2.Centrioles for spindle fibres
3.Chromosomes shorten and thicken making them visible
4.Nuclear envelope begins to disintegrate
What is the metaphase?
The second stage of mitosis
What happens in the metaphase
1.Chromosomes line up along the equator of the cell
2.Spindle fibres attach to the centromere
When does the anaphase occur
After the metaphase.(third stage in mitosis)
What happens in the anaphase
1.Spindle fibres begin to contract
2.Sister chromatids begin to be pulled apart and move to opposite poles
