  5. 4. Which of the following activities occurs in the S phase? • growth of the cell • replication of the DNA • formation of the mitotic spindle • breakdown of the nuclear membrane

  6. 5. Mutations within a DNA sequence are • unnatural processes that are harmful to genetic diversity • natural processes that produce genetic diversity • unnatural processes that always affect the phenotype • natural processes that always affect the phenotype

  7. 6. Which of the following base pair sequences could be produced in DNA replication? • 5' AGTCUT 3'3' TCUGTA 5' • 5' AGTCAT 3'3' CTGACG 5' • 5' AGTCAT 3'3' TCAGTA 5' • 5' AGTCAT 3'3' UCAGUA 5'

  8. 7. A student looking through a light microscope saw this cell in cytokinesis. This cell is most likely from — • a plant • a virus • An animal • A bacteria

  9. 8. The diagram is of an untwisted DNA molecule. Which part is the strong covalent bond? • A • C • E • F • G • I

  11. 10. The diagram below shows Rosalind Franklin’s x-ray diffraction image of DNA.How did this evidence affect the work of Watson and Crick? • It was used to show that DNA was the molecule of inheritance • It was used to develop the theory of independent assortment • It was used to identify the four bases that make up DNA • It was used to determine the physical structure of DNA

  12. 11. During DNA replication, the wrong nucleotide was inserted in the DNA sequence. Which of the following terms describes this situation? • mutation • regeneration • transcription • translation

  13. 12. studied nucleotides • Chargaff • Franklin • Watson & Crick

  14. 13. What phase of Mitosis is this? • Prophase • Anaphase • Metaphase • Cytokinesis • Telephase • Interphase

  16. 5' G T A _ _ _ A A 3'3' C A T G C A T T 5'15. This segment of DNA has undergone a mutation in which three nucleotides have been deleted. A repair enzyme would replace them with • GTA • CTG • GCA • CGT

  17. 16. Semi-conservative replication of DNA refers to the idea that • each half of the original DNA molecule is joined with a new complementary DNA strand • each new DNA molecule contains two new single RNA strands • DNA molecules need to unwind before duplication begins • the two strands of DNA molecules run in opposite directions

  18. 17. Which of the following activities occurs in the G1 phase? • growth of the cell • replication of the DNA • formation of the mitotic spindle • breakdown of the nuclear membrane
