Lesson 10: Virus Release
Virus release is the final step in the viral replication cycle, where newly formed virions exit the host cell to infect new cells. The release mechanism varies depending on the…
Lesson 9: Virus Maturation
Virus maturation is the final stage of the viral life cycle where newly assembled virions undergo biochemical and structural changes to become fully infectious. Maturation is crucial because, in many…
Lesson 8: Virus Assembly
Virus assembly is the process by which newly synthesized viral components—genomic nucleic acids and structural proteins—come together to form new virions (complete virus particles) within an infected host cell. This…
Lesson 7: Virus Genome replication and Gene expression
Virus genome replication and gene expression are critical steps in the viral life cycle that enable the production of new viral particles. These processes vary depending on the type of…
Lesson 6: Virus Uncoating
Virus uncoating is the process where a virus sheds or removes or alters its protective protein coat (capsid) to release its genetic material inside a host cell, initiating the infection.…
Lesson 5: Virus Internalization
Virus internalization or entry or penetration is the process during which viruses gain access to viral replication sites within uninfected cells, a multistep course of events that starts with binding…
Lesson 4: Virus Attachment (adsorption)
Viruses attach to proteins known as cellular receptors or attachment factors on the surface of the host cell All viruses react specifically with a receptor on a cell surface using…
