RNA => protein Molecular Biology DNA => ! RNA => protein Modern Biology sequence => ! structure => function Lecture 1. Protein Structure IS SOMETHING HAPPENING? HOW DO WE KNOW? CAN WE PREDICT WHETHER IT WILL HAPPEN? Equilibrium Constants and Rates k for [B] eq A <---> B K = _____ k rev [A] eq WE NEED TO MAKE MEASUREMENTS! Equilibrium Constants and Free Energies k for K = [B] eq A <---> B ____ k rev [A] eq Δ G˚ = G B- G A = -RTlnK Equilibrium Constants and Free Energies k for K = [B] eq A <---> B ____ k rev [A] eq Δ G˚ = G B- G A = -RTlnK Rememeber, for ∆ G you need to COMPARE the free energies of beginning AND ending states => MUST KNOW ABOUT BOTH What do free energies have to do with molecules?...
