About this video
Discover how viral structure dictates infection, immunity, and transmission — learn viral structure, genomes, capsids, envelopes, and replication basics. This concise explainer breaks down virus biology using clear analogies and key technical terms like capsid, nucleocapsid, positive-sense and negative-sense RNA, segmented genomes, reverse transcriptase, and viral glycoproteins. You’ll understand how genomes (DNA or RNA, single- or double-stranded, segmented or non-segmented) act as the “software” that hijacks host machinery, while capsids and envelopes serve as protective and delivery “hardware.” See why…
