Document Summary
Test dates confirmed thur feb 4 and thur mar 4. Correction from last lecture smallest virus is the circle virus (2 kb), not parvovirus (4-6 kb) Grouped by genome type and replication strategy. - indicates that you should know it but not in detail: indicates that you should know all the details from the table ssdna viruses. All very small (<= 2 = 9 kb), most circular (no free ends therefore more protected from exonucleases) Some genomes are segmented (fragmented - think of chromosomes when you think of segments) None have envelopes and most have icosahedral capsids. Infect: vertebrates, invertebrates, plants, prokaryotes (everything but lower eukaryotes) dsdna viruses. Large variation in genome size (5 1. 2 mb) dna more stable and can repair mistakes. Linear or circular genomes none segmented (all one piece of dna) Capsids mostly icosahedral and may or maynot contain an envelope. Infect: vertebrates, invertebrates, lower eukaryotes, prokaryotes (table 3. 2) [& plants (eg. camv) table 3. 6]
