Waiting for results of an AIDS test is considered too late. They cause a decrease in the concentration of PRPP, thus antagonizing salvage pathways. They cause an increase in the concentration of PRPP, thus promoting salvage pathways. They cause a wasteful increase in the concentration of the reaction intermediates. All of the above statements are correct.
NNRTase inhibitors are chemically reactive and covalently inactivate the reverse transcriptase.
Protease inhibitors prevent the decoating of viral RNA upon the entry of a virion into a cell. Protease inhibitors prevent the proper processing of the viral polyprotein precursor, which is necessary for the proteins to be incorporated into new infectios virions. NNRTase inhibitors are best used alone because they interfere with the action of other anti-AIDS drugs. Combination therapy is essential to prevent emergence of resistance. None of the abov e. 16.
