Q

Interphase

A

Cells grows rapidly and DNA is synthesized

17
Q

Parts of M Phase

A 
Prophase
Metaphase 
Anaphase
Telophase
Cytokinesis
18
Q

Prophase (of mitosis)

A
  • Chromatin condenses
  • nuclear membrane breaks
  • mitotic spindles grow from centrioles
  • centrioles move to poles
19
Q

Metaphase (of Mitosis)

A
  • spindle attach to chromosomes

- chromosomes positioned along center of the cell

20
Q

Anaphase (of Mitosis)

A
  • sister chromatids pulled apart at centromeres

- chromosomes pulled to opposite poles

21
Q

Telophase and Cytokinesis

A
  • nuclear envelope forms
  • mitotic spindles disassemble
  • cells split
22
Q

Mitosis produces…

A

Two identical daughter cells, each containing a full set of genetic information

23
Q

Homologous Pairs

A

Pair of chromosomes that carry the same genes
