- 2. Multiple ChoiceWatson and Crick were the first to suggest that DNA is _____a short moleculethe shape of a double helixa protein moleculethe genetic material
- 3. Multiple Choice
How did Rosalind Franklin's photo 51 affect the work of Watson and Crick? (picture is shown)It was used to determine the physical structure of DNAWatson kept it under his pillow for inspirationIt was used to determine the theory of independent assortmentIt was used to show DNA was the molecule of inheritance - 4. Multiple ChoiceFrederick Griffith worked with two types of ________ bacteriaparameciumE. colistreptococcusacidophilus
- 5. Multiple ChoiceS-strain bacteria that Griffith worked withcaused pneumoniahad a smooth appearancekilled miceall of these
- 6. Multiple ChoiceGriffith discoveredthat DNA was the genetic materialthat R-strain had transformed into S-strainthat x-rays can take pictures of DNAthat mice aren't very good for genetic studies
- 7. Multiple ChoiceOswald Avery discoveredDNA was the transforming principlethat there is more phosphorus in DNA than in proteinhow viruses workthat Watson stole a photo from Franklin
- 8. Multiple ChoiceThe two scientists that confirmed that DNA was what bacteriophages inject into bacteria wereHershey and ChaseWatson and CrickFranklin and WilkinsNestle and Quick
- 9. Multiple ChoiceThe name given to the shape of DNA isdouble helixalpha spiralcorkscrew laddertwisty slide
- 10. Multiple ChoiceWho took the definitive picture of DNA using x-rays?Rosalind FranklinJames WatsonErwin ChargaffBenjamin Franklin
- 11. Multiple ChoiceWhich of these scientists did not win a Nobel Prize for the discovery of DNA structure?Rosalind FranklinJames WatsonFrancis CrickMaurice Wilkins
- 12. Multiple ChoiceThe work of scientists including Griffin, Avery, Hershey & Chase and Franklin helped us to determine the __ are responsible for carrying genetic material.Amino AcidsProteinsNucleic AcidsCarbohydrates
- 13. Multiple ChoiceFrom his work with mice and pneumonia-causing bacteria, Frederick Griffin coined the termReplicationTranscriptionTransformationTranslation
- 14. Multiple ChoiceHow did Hershey and Chase's use of radiolabeled bacteriophages to study the genetic material validate Avery's research?It demonstrated conclusively that the genetic material is not protein.It showed that bacteriophages are not digested by bacterial enzymes.It proved that bacteria will take up phosphorus, but not sulfur.It confirmed that bacteriophages cannot inject radiolabeled DNA.
