Summary
Attachment, entry, replication, assembly and release; phages follow lytic or lysogenic cycles.
In depth
Steps: attachment, penetration, uncoating, genome replication and gene expression, assembly and release (lysis or budding). Lytic phages burst host cells; lysogenic phages integrate as prophages and replicate with the host.
Cell tropism depends on receptors and proteases. RNA viruses make RNA-dependent RNA polymerases. Release by budding gains the envelope from host membrane.
Key idea: viruses use host ribosomes to make viral proteins.
Frequently asked questions
What is Viral Replication Cycle?
Attachment, entry, replication, assembly and release; phages follow lytic or lysogenic cycles.
Which area of biology covers Viral Replication Cycle, and how advanced is it?
Viral Replication Cycle is one of the 52 topics in Immunology & Disease. It is rated Intermediate, so it suits learners who already know the core vocabulary. Related topics in this area include Virus Structure, Viruses, Retroviruses.
Can you give an example of Viral Replication Cycle?
Herpesviruses establish latency in nerve cells.
What should I learn before Viral Replication Cycle?
Work through the Beginner topics in Immunology & Disease first, such as Immune System, Viruses, Innate Immunity, then return to Viral Replication Cycle. Intermediate topics assume the Beginner vocabulary.
What topics are related to Viral Replication Cycle?
The closest topics to Viral Replication Cycle are Virus Structure, Viruses, Retroviruses, Phagocytosis. Comparing them side by side is a good way to see how the ideas connect.
How can I check that I understand Viral Replication Cycle?
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Viral Replication Cycle. To practise the whole of Immunology & Disease, use the Immunology & Disease quiz.
How is Viral Replication Cycle different from Virus Structure?
Viral Replication Cycle: Attachment, entry, replication, assembly and release; phages follow lytic or lysogenic cycles. Virus Structure: A nucleic acid genome enclosed in a capsid, sometimes with an outer lipid envelope and spike proteins. Read both side by side and note what each one explains.
How should I study Viral Replication Cycle step by step?
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Virus Structure and explain the difference aloud. Finally, take the Immunology & Disease quiz and come back to this page for any question you miss.
