Hiv's genome of rna includes the code for reverse transcriptase (rt), an enzyme that acts early in infection to synthesize a dna genome off of an rna template. the hiv genome also codes for protease (pr), an enzyme that acts later in infection by cutting long viral polyproteins into smaller, functional proteins. both rt and pr represent potential targets for antiretroviral drugs. drugs called nucleoside analogs (na) act against rt, whereas drugs called protease inhibitors (pi) act against pr. which of the following treatment options would most likely avoid the evolution of drug-resistant hiv (assuming no drug interactions or side effects)?

(a) use a series of nas, one at a time, and change about once a week.

(b) use a single pi, but slowly increase the dosage over the course of a week.

(c) use high doses of na and a pi at the same time for a period not to exceed one day.

(d) use moderate doses of na and two different pis at the same time for several months.

(d) Use moderate doses of NA and two different PIs at the same time for several months.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
