3. DNA Structure & Function
The structure of an organism and its parts are often designed so as to maximize the ability to perform certain functions. How does the structure of DNA facilitate its functions of accurate replication and information storage? Why do you think DNA is diffuse during interphase yet condensed during other stages of mitosis/meiosis? Answer these questions in paragraph form, using only the space provided.
4. Transcription / Translation Problem
In the following portion of DNA, suppose that a transversion mutation occurs at the indicated point(*). Please state what amino acid would result if the mutation had not occurred, and then what amino acid results when it does occur. (* Remember, there is more than one possible outcome.)
