AZT, used in treating AIDS, is an effective inhibitor of nucleic acid synthesis because: a. It has a nitrogen group instead of a 3' OH. b. It is a 2', 3' dideoxy compound. c. It doesn't form good base pairs. d. It inhibits RNA Polymerase needed to make RNA for new HIV virus particles. e. More than one of these is correct.

answer: blah

explanation:

bc blah

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
