Viruses…not as ugly as they act

Explore the intricate process of viral replication and how viruses, such as AIDS, polio, and flu, attach, invade cells, copy, and release. Learn about attachment mechanisms, reverse transcription, integration with host DNA, translation, protease action, and viral assembly. Discover both active and latent viral forms.

Presentation Transcript

  1. Viruses…not as ugly as they act A viral disease or two….AIDS, polio, rabies, mumps, flu, measles Viral Replication 1. ATTACH virus attaches to the cell 2. INVADE nucleic acid injects itself into the cell 3. COPY nucleic acid takes over the cell and starts making virus parts 4. RELEASE cell bursts open……….repeat steps 1 - 3.

  2. ATTACHMENT Active form – constantly replicating Latent form – not replicating…waiting

  3. 1. ATTACHMENT Getting in 2. REVERSE TRANSCRIPTION From viral RNA to DNA 3. INTEGRATION, TRANSCRIPTION a. Viral DNA joins host DNA b. Making multiple viral RNAs 4. TRANSLATION Producing viral proteins 5. VIRAL PROTEASE Cleaving viral proteins 6. ASSEMBLY & BUDDING Getting out
