Q
  • longest phase
  • chromosomes start to shorten and thicken
  • nucleolus gradually disappears means the cell is preparing for cell division.)
  • centrosome moves toward the separate end/pole (mitochondria and other organelle, being removed)

Q
  • spindle fibers start to shorten and go back to the centrosome
  • sister chromatids separate and moves toward the separate poles ( centrosome
    > so there would be representatives on each side, divide equally
A

Anaphase

17
Q
  • last stage of mitosis
  • arrival of chromatids towards the separate poles.
  • nuclear membrane and nucleolus, re-form
  • mitotic apparatus disappears
  • replication of chromosomal material
A

Telophase

18
Q

sister chromatid will make another chromatid so that?

A

the structure of the chromosome will be complete

19
Q
  • division of the cytoplasm to form two separate daughter cells
A
