Problem Set 5 Due Thursday 6 October For the following problems, BRIEF answers are requested; in fact, bullet points are preferred! You may need to use resources other than our textbook (such as the BBC video shown in class and/or the internet) to answer these questions. 1. What is Chargaff’s rule, and what insight did it provide to Watson & Crick? 2. Under what conditions does DNA assume the A, rather than the B form? Which is most likely to be biologically active? 3. What force holds the base pairs together in the middle of the helix? What are the differences between AT and GC pairs with respect to this pairing? 4. What is the backbone of DNA? 5. Define and/or describe the antiparallel nature of double stranded DNA.

In what direction (5’ to 3’ or 3’ to 5’) does a DNA polymerase move along the DNA template strand? How do organisms solve the problem that all DNA polymerases move in the same direction along the template strand, yet double-stranded DNA is antiparallel?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
