  1. Cell Cycle UnitPractice Test

  2. 1. What is the purpose of mitosis? • To create 2 new cells • To divide the chromosomes • To grow the organism • To make sure cells are small

  3. 2. Which of these does NOT explain why interphase is needed? • It replicates the DNA. • It doubles everything so the cell can split into identical cells. • It divides the cell. • It makes proteins & organelles.

  4. 3. Which is NOT a reason why cells divide? • Multicellular organisms can grow • To replace damaged cells • To decrease surface area to volume ratio • To be more efficient

  5. 4. When does DNA replication occur? Choose all that apply. • Between cell divisions • S phase • Interphase • Prophase

  6. 5. How can you tell if the new strand is the leading strand? Choose all that apply. • It is always on the right. • It travels from 3’5’. • It is built continuously. • It is built discontinuously. • It is built towards the helicase.

  7. 6. What is the name of the enzyme that connects the nucleotides? • Helicase • DNA polymerase • Cyclins • P53 • DNA ligase

  8. 7. Which of these is FALSE about mitosis? • It involves the destruction & formation of a nuclear membrane • It makes two cells • It makes two nuclei • It occurs during cell division

  9. 8. Which of these are involved in cell division? • Mitosis • Interphase & Mitosis • Mitosis & Cytokinesis • DNA replication & Mitosis

  10. 9. When do centrioles move to opposite ends of the cell? • Prophase • Metaphase • Anaphase • Telophase • Cytokinesis

  11. 10. When does excision repair take place during the cell cycle? • Prophase • Metaphase • G1 • G2 • S phase
