Question

It is difficult to make antiviral drugs because
a. Viruses use the host cell's machinery to grow and divide.
b. Viruses are surrounded by protein coats.
c. Viruses are one of the borderlines of living and non-living states.
d. Viruses are very small in size.

Answer 1

Antiviral drugs are a class of medicine utilized for treating viral diseases. Most antivirals target explicit infections, while an expansive range of antivirals is compelling against a wide scope of infections. In contrast to most anti-infection agents, antiviral medications do not annihilate their objective microorganisms; rather they restrain its turn of events.

Complete answer:
- It is harder to make antiviral drugs than making antibiotics because infections have scarcely any biochemical instruments of their own. They enter the host cells and utilize their apparatus for their life measures.
- In this way, antiviral drugs will neutralize the host body. Anti-toxins block bacterial amalgamation pathways without influencing the body since microorganisms utilize its own metabolic pathway hardware along these lines, it will not influence the host body.
- There is another distinction that makes infections harder to focus on drugs than microbes: their propensity to transform all the more frequently and rapidly, delivering any medication focusing on the less strong.

Hence, the correct answer is option (A).

Additional information:
- Viral genomes are encircled by protein shells known as capsids. A question arises what is how capsid proteins perceive viral, yet not cell RNA or DNA. The appropriate response is that there is frequently some sort of "bundling" signal (grouping) on the viral genome that is perceived by the capsid proteins.
- As viruses respond like non-living in the free environment however when they enter the body of a living life form then they show the highlights of a living creature and start multiplication.
- A virus is an irresistible operator of little size and basic creation that can duplicate just in living cells of creatures, plants, or microbes. They range in size from around 20 to 400 nanometres in width.
- However, these points do not differ from making antiviral drugs with antibiotics.

Note: Viruses are nonliving outside the host cells and become living inside the host as it utilizes the host's cells as hardware to reproduce. This property of infection makes it hard to track down focuses on the drug that would meddle with the virus without additionally hurting the host living being's cells. The explanation is that infections have not many biochemical systems of their own. They enter the host's cells and utilize the host's cell hardware for their life measures. This infers that there are hardly any virus explicit focuses to aim at.
