5 True/False Questions

  1. How many types of amino acids are there?Only one


  2. Why is the structure of a DNA molecule described as a zipper?Because like a zipper being held together by the teeth, the two chains of nucleotides are held together by nitrogenous bases


  3. What does Messenger RNA do?Transcribes information from the DNA in the nucleus and carries it to the cytoplasm, and then to the ribosome


  4. What is translation?The process of making RNA from DNA


  5. What was Hershey and Chase?Scientists who made models of molecules with structures to fit the data that Rosalind Franklin had discovered
