Question
That many transition-state analogs bind more tightly than the native substrate reinforces the concept that transition-state analogs are planar structures. State analogs are highly charged at physiological pH. binding to the transition state is through a lock-and-key-mechanism. transition-state analogs are hydrophobic. binding to the transition state is through an induced-fit mechanism. The K_M is equal to the product concentration at initial reaction conditions. equal to the substrate concentration when the reaction rate is half its maximal value. proportional to the standard free energy. All of the above. None of the above. How many different sequence possibilities are there for a DNA polymer that is 10 bases long? 320 32,000 1,048.576 100,000 After two generations of replication in the Meselson and Stahl experiment, what was the composition of the two bands? One band was all ^14N and one ba nd was all ^15N. One band was all ^14N and one band was half ^14N and half ^15N. One band was all ^15N and one band was half ^14N and half ^15N. One band was all ^14N and one band was one quarter ^14N and three quarters ^15N. One band was all ^15N and one band was one quarter ^14N and three quarters ^15N. You perform melting experiments on double stranded DNA, starting at low salt concentrations (~0.2 M NaCl) and then increasing the salt concentration to about 0.6 M NaCl. How does salt concentration affect the T_m of the DNA? Salt at these low concentrations has no effect on T_m. Increasing salt causes a decrease in T_m due to the stabilizing actions of the salt. Increasing salt causes an increase in T_m due to the destabilizing actions of the salt. Increasing salt causes a decrease in T_m due to the destabilizing actions of the salt. Increasing salt causes an increase in T_m due to the stabilizing actions of the salt.Explanation / Answer
