Question

Quizplus · Accepted Answer

There are seven fundamental groups of virus species based on their mechanisms of replication and mRNA expression, as defined by the Baltimore classification system. This system categorizes viruses into seven classes based on their type of genetic material (DNA or RNA), whether their genetic material is single-stranded or double-stranded, and their method of replication.
