Question

virus are also called biological puzzle why?l

Answer 1

Foremost, viruses are neither living nor non-living. They are simply inanimate, complex organic matter and can’t even multiply on their own. Yet, they manage to infect and hijack the host cell machinery so as to make copies of the virus.

Many viruses have this knack of evading the immune system by constantly changing their genetic material. So whatever Antigenic peptide was presented (if any) by and to the cells of immune system for generating a response against these viruses, cannot be used for carrying out an immune response with substantial intensity, because the genetic sequences of the virus has changed.

I hope this will help u

Answer 2

Viruses show the properties of both living and non-living things, hence it is difficult to classify them as so. Therefore, they are considered to be a biological puzzel.They are living entity which cannot survive on their own except with the presence of an host.
