How Well You Know DNA Structure? Quiz

How well you know the DNA structure? When it comes to reproduction, the parents' DNA split and is shared with the offspring, so it comes out with having characteristics from the parents. Understanding Human DNA has made it possible to understand how some illnesses are hereditary and if they can be avoided. In this quiz, you will be expected to test out what you know about different components of DNA. Do check it out!

      Alternating phosphates and sugar molecules

    • B. 

      Nucleotides

    • C.

  • 6. 
    The diagram below represents Griffith's experiment on mice. Which of the following would be a logical conclusion to this experiment?
    • A. 

      The rough strain of bacteria is deadly after all.

    • B. 

      The rough strain of bacteria must have mutated to become deadly.

    • C. 

      Something inside the bacteria has the ability to instruct and control what the bacteria does. Therefore, changing a bacteria's behaviors if engulfed by that bacteria.

    • D. 

      Proteins inside the bacteria must have a transforming ability.

  • 7. 
    The following diagram represents what Hershey and Chase experimented in the 1950s. Which of the following hypotheses did they test and confirm? (make sure all the hypothesis is a true hypothesis first!)
    • A. 

      If DNA is truly the hereditary material emitted into the bacteria, then radioactively marked DNA will show up in the bacteria, not in the external liquid following the virus' activity.

    • B. 

      If a relationship exists between a virus' DNA and protein, then marking the protein with radioactive material will help identify the bacteria's life cycle.

    • C. 

      If a relationship exists between DNA and its ability to be transmitted, then tracking the DNA with radioactive material will note how the bacteria was changed in the mice.

    • D. 

      Protein and DNA could possibly be related to hereditary behaviors and therefore, marking each one will help identify which one causes the bacteria to be transformed.

  • 8.

    • A. 

      Adenine or Guanine

    • B.

    • C. 

      Thymine or Guanine

    • D. 

      Thymine or Adenine

  • 9.

    • A. 

      A bonds with T, C bonds with G ALWAYS

    • B. 

      A and G will always have double rings in their molecules

    • C. 

      A bonds with C and G bonds with T

    • D. 

      No such rule exists

  • 10.
