Document Summary
In uenza virus genomes are rna, yet they replicate in the nucleus. Taxonomy of viruses (ictv) virus taxonomic units: order, family, genus, species: viruses we work with in the lab are isolates of species to date, over 6,000 viruses classi ed in 2818 species have been identi ed. Taxonomic criteria genome organization and replication nucleic acid characteristics intracellular location of replication, presence or absence of dna intermediate once know genome can know entire replication cycle. How are viruses classi ed: two classi cation schemes, the classical system (see fig. Different kinds of nucleic acids out there. Entrez genomes: 5117 reference sequences - 3733 viral genomes. Iv: go through rna intermediate: use reverse transcriptase. Review: important concepts in molecular virology (and life!: replication: to make new genome copies (dna or rna, transcription: dna or rna template is transcribed into mrna, translation: mrna is translated into protein. There are exceptions in the world of viruses since many have rna genomes.
