The cell cycle

Question 1

stages of the cell cycle

Answer 1

interphase, mitotic phase (prophase, metaphase, telophase), cytokinesis

Question 2

interphase

Answer 2

• G1: growth (of cell and replication of organelles)
• S: DNA synthesis ( semi conservative replication)
• G2: more growth
• 90% of cell cycle spent in interphase

Question 3

prophase

Answer 3

nuclear envelope breaks down and nucleolus disappears
- chromosomes coil
- microtubules form

Question 4

metaphase

Answer 4

• chromosomes are maximally condensed and line along the equator
• attached to spindle by centromere

Question 5

anaphase

Answer 5

• chromosome separated to chromatids at the centromere
• pulled of opposite pole

Question 6

telophase

Answer 6

• chromatids decondense
• nuclear envelope forms and cell splits
• two identical daughter cells are formed
