EvolutionWe discuss the different parts of the infectious cycle and how to study them
Emerging virusesThe viral genome is the blueprint for making new virus particles. We review seven types of DNA and RNA viral genome
Viral ecologyVirus particles are constructed in three ways: with helical, icosahedral, or complex symmetry.
HIV and AIDSViruses must enter cells to replicate, but they are too large to pass through the membrane of the cell.
Unusual infectiousRNA virus genomes are copied into mRNA by a viral enzyme, RNA dependent RNA polymerase.
Therapeutic virusesLynda Coughlan reviews how oncolytic viruses, which specifically kill tumor cells, are designed and how they work.
