Packet 3: Bonus 14

The two-state transition model explains how these molecules conform to helix and coil states. For 10 points each:

[10e] Name these long molecules that include nucleic acids. Nylon is a synthetic type of these molecules.

ANSWER: polymers

[10m] The two-state model assumes each monomer displays a “maximum” form of this phenomenon, causing the entire polymer to be coiled or helical. The Hill equation calculates the degree of this phenomenon during binding.

ANSWER: cooperativity [or being cooperative or cooperation; accept maximum cooperativity; accept cooperative binding]

[10h] In a helix–coil transition model named for J. K. Bragg and this scientist, the cooperativity of each monomer and its neighbor is assigned a specific statistical weight. A polymer’s molecular mass can be determined using a plot named for this scientist constructed from SLS data.

ANSWER: Bruno Zimm [or Bruno Hasbrouck Zimm; accept Zimm–Bragg model or Zimm-Bragg notation; accept Zimm plot]
