Mitosis / Meiosis

Question 1

S phase

Answer 1

Prior to Mitosis/Meiosis

DNA replicates

Question 2

Prophase

Answer 2

• Chromatin condenses into chromosomes
• Centrioles form and spindle fibers form
• Nuclear envelope breaks down

Question 3

Metaphase

Answer 3

• Chromosomes line up on metaphase plate
• Centrioles are attached to spindle fibers

Question 4

Anaphase

Answer 4

• Centrioles split
• Sister chromatides are pulled apart

Question 5

Telophase

Answer 5

• Cell membrane pinches in half
• Nuclear envelopes reform
• 2 indentical daughters produces
  
  • If diploid cell undergoes mitosis –> 2 dipoloid (2n) cells are produced
  • If haploid cell undergoes mitosis –> 2 haploid (n) cells are produced
