  1. MICR. 402 Lecture 5 January 17, 2008

  2. Chapter 2 - Virus Replication Bacterial growth - binary fission

  3. Chapter 2 - Virus Replication One step growth curve Latent period time until progeny virus released from infected cells - don't confuse with latency of herpes viruses Eclipse period time when no complete virus inside cells - infectivity = nil if disrupt infected cells

  4. Chapter 2 - Virus Replication What’s happening during eclipse and latent phases? Early protein synthesis Replication of genome Late protein synthesis Assembly of virions Release

  5. Chapter 3 - Genomes Use chapter as reference.

  6. Chapter 4 - Virus Structure

  7. Chapter 4 - Virus Structure

  8. How are genomes protected? - Genomes need to be protected from degradation by RNAses, DNAse, or restriction enzymes, or damage by UV radiation. - Condensation protects against RNAses, DNAse, and also association with proteins is key in protecting the genome.
