19
Q

Interphase

A 
period when cell is not dividing
-G1: duplicates organelles
-S: DNA is replicated
-G2: Grows
(Grow, replicate, grow)
20
Q

Order of mitosis

A
  • Prophase
  • Metaphase
  • Anaphase

21
Q

Prophase

A
  • Nucleolus and nuclear envelope disappear

  • Spindles form
22
Q

Metaphase

A

-Chromosomes line up in the middle of the cell

23
Q

Anaphase

A

-Chromatids are pulled apart

24
Q

Telophase

A
  • Chromosomes uncoil and become chromatin
  • Nucleolus and Nuclear Envelope reappear
