What is the primary method by which naked or enveloped viruses penetrate host cells?
Endocytosis
Test your knowledge on the different steps involved in viral replication, from adsorption binding to synthesis of genome and proteins. Learn about how viruses bind to receptors, penetrate cells, and replicate their genetic material. Identify the mechanisms used by enveloped and naked viruses during penetration and uncoating.
