Exercise 13

Select one of the enzymes involved in DNA replication (see Chapter 2).
a. Describe the function of the enzyme.
b. Search the National Center for Biotechnology Information (NCBI) STRUCTURE database for a three-dimensional structure of the enzyme. Print a copy of the enzyme structure and attach it to your homework set. (http://www.ncbi.nlm.nih.gov/Structure/).
c. How do you think the structure of this enzyme facilitates its function?
d. Note: To print the file, open the structure file in Cn3D and select the view that you want to save. Select "File/Export PNG" and it will ask you for a file name and folder location that you want to save. When it is saved, you can go to the saved folder and double click on the file name; it should open up in a default image viewer. When the image is visible then <right click> and select "print."
