AP Biology Quizzes & Trivia

The human DNA is a very interesting subject and few know the secrets it holds. Over the course of studying chapter 25 we got to unlock and understand a lot about it. The quiz below is designed to test out just how much you can remember. Give it a try and widen your understanding.

    Before Watson and Crick described DNA structure, Linus Pauling proposed a possible model with three strands of support running down the middle and the bases extending out the sides. How close was his guess?
    • A. 

      He just missed the number of support strands, which was two rather than three.

    • B. 

      The support strands ran along the outside rather than down the center.

    • C. 

      The bases were paired in the middle rather than sticking out the sides.

    • D. 

      All of the above varied from the real model.

  • 5.

      Attracts tRNAs with appropriate amino acids.

    • B. 

      Must first undergo replication

    • C. 

      Contains anticodons that must become codons.

    • D. 

      Serves as a template for the production of mRNA.

    • E. 

      Adheres to ribosomes for protein synthesis.

  • 6.
