Viruses are classified into many groups based on:

Explanation

Viruses are extremely diverse and do not fit into the typical classification systems used for cellular organisms. To properly study and identify them, scientists classify viruses based on several important characteristics:Nucleic acid type (DNA or RNA, single-stranded or double-stranded) helps determine their replication strategies and genetic properties.Capsid symmetry (helical, icosahedral, or complex) gives insight into their structure and stability.Host cell infectivity distinguishes viruses based on the organisms they infect, such as bacteria (bacteriophages), plants (plant viruses), or animals/humans (animal viruses).
