BIOL 4190 : Midterm Exam
Document Summary
Chapter 4 slide 5- vertical and horizontal transmission: vertical from parent to members of next generation, horizontal non-vertical transmission. Fever virus: know examples slide 19- transcription of rna virus genes, rna viruses encode own rna-dependent rna polymerase for their mrna production, although cells of plants and other euk. Transcriptase: cell produced enzymes, dna dna, dna-dependent dna polymerase, dna rna, dna-dependent rna polymerase (rna pol. ) , and for (-) stranded rna viruses the reverse is true. Stimulation of production of major histocompatibility (mhc) class i molecules and proteasome proteins: these molecules enhance the presentation of viral peptides on the infected cell surface to t cells. Quasi species slide 15- criteria in modern classification: based primarily on properties of the virus particle, genetic material is most important!, form of nucleic acid, ssdna (+ or - strand) Dsdna: ssrna (+ or - strand) No immune response to pathogen (prion is a host protein!: behaves in extracts as very low molecular weight entity.
