Aminoglycosides: are amino modified sugars that changes shape of 30S sub-unit causing incorrect pairing of transfer Ribonucleic
acid or tRNA anticodons with messenger Ribonucleic acid or m RNA codons. Hence, the correct answer is Aminoglycosides.
Antisense nucleic acids: blocks ribosome attachment to messenger Ribonucleic acid or mRNA.
Hence, the correct answer is Antisense nucleic acids.

Cocktail is a combination of several antiviral drugs, which are used to treat AIDS (acquired immune deficiency syndrome)
and are more effective than using a single agent. This is because the HIV (human immune deficiency virus) will mutate or
change a lot. So, using single drug can be effective against one mutation. By using cocktail of drugs it is easy to attack the
virus at different points in the life cycle of virus and the patient compliance in taking the medicine is improved.
There are different sites of inhibition like:
1. Inhibition at viral fusion into the cell.
2. Reverse transcriptase enzyme inhibition.
3. Protease enzyme inhibition.

Penicillium is a mold belongs to fungus. Penicillin secreted by the Penicillium acts against bacterial cell wall and toxic to the bacteria,
but not to fungus. The cell wall of bacteria is made up of peptidoglycan; penicillin blocks the formation of peptidoglycan.
Fungus is a eukaryote and doesn’t contain peptidoglycan. So, penicillin cannot act against Penicillium.
By this way Penicillium escapes the effects of penicillin it secretes.

For the effective treatment of diseases that are infectious. The physicians must be familiar with the specificity of effectiveness,
about the pathogen. To access the microbial efficacy variety of test are included, like diffusion test. In Kirby-Bauer susceptibility test,
the presence of a zone of inhibition around disks containing antimicrobial agents indicates that the microbe does not grow in the
presence of the agents. Zone of inhibition is greater and the drug is effective. So, the Kirby-Bauer susceptibility test does not depend
upon the microbe that grows well in the presence of agents, smallest amount of the agent that inhibit microbe growth, and minimal
amount of an agent. Hence, option ‘b’, ‘c’, and ‘d’ is incorrect.
