Why would a drug that damages capsids help treat a viral infection

zvonat [6]

The capsid is the protein shell that surrounds the core of a virus where its nucleic acid is located. The capsid is made up small sub units called capsomeres. A virus consists of a nucleic acid which may either be RNA or DNA and is found in varying quantities in the virus. It is this nucleic acid that is vital to the virus' survival that is housed in the capsid. A drug that targets the capsid and damages it will cause the nucleic acid to leak out of the virus and into the surrounding while other fluids foreign to the virus will get in rendering the virus totally impaired, and due to this the virus cannot survive but will speedily die.

It is possible to think of a species' habitat as the outward representation of its biological niche. As a result, "habitat" refers to a particular species, which is fundamentally distinct from ideas like "environment" or "vegetation assemblages," for which the term "habitat-type" is more applicable.
