interphase
What is the first portion of the cell cycle?
interphase
What is the second portion of the cell cycle?
prophase
What is the third portion of the cell cycle?
metaphase
What is the fourth portion of the cycle cycle?
anaphase
telephase/cytokinesis
What is the G1 (first gap) phase?
The cells grows and carries out normal functions
it condenses
What are opposite poles of the cell?
centrosomes
What do sister chromatids do?
they sperate and move to opposite sides of the cell
what happens to the chromosomes in telephase?
they become less condensed
What is the S (synthesis) phase?
DNA and chromosomes replication occurs
What happens to the nucleoli?
it disappears
Where do chromosomes line up during this process?
the metaphase plate
it enlongates
During cytokinesis, do plants or animals form a cell plate?
plants
What is the G2 (second gap) phase?
final growth and preparation for mitosis occurs
How do duplicated chromosomes appear?
as sister chromatids
What do microtubules attach to?
kinetochore
What form are the chromosomes in?
sister chromatids
What forms in telephase?
two daughter nuclei
What percentage of the cell cycle does interphase take place?
90%
What happens to the centrosomes?
they move away from each other
Where do microtubules enter?
in the nuclear area
How do the chromatids sperate and move?
what reappears in telephase?
nucleoli
