Question

what is a virus?? write 5 lines about it.​

Answer 1

Answer:

A virus is genetic material contained within an organic particle that invades living cells and uses their host's metabolic processes to produce a new generation of viral particles.

The way they do this varies. Some insert their genetic material into the host's DNA, where it can sit in wait until it's translated at a later date. As the host cell replicates itself, it can make new viruses.

Viruses can also burst their host cell as they expand in numbers, in what's called a lytic cycle of reproduction.

The word virus comes from a Latin word describing poisonous liquids. This is because early forms of isolating and imaging microbes couldn't capture such tiny particles.
