BIOL 2051 Chapter : Group 1 7 Viruses
Document Summary
Single stranded: herpesvirus group - cold sores, venereal disease, poxvirus group - smallpox (vaccinia), cowpox, remain latent in the body for years, becoming, parvovirus, double stranded rna, rotavirus- member of reovirus family, most. Requires host dna polymerase to make complimentary dna. Uses it sown or host dna polymerase chicken pox common cause of infant diarrhea. Uses viral rna-dependent rna polymerase to make mrna & genomic rna. Usually package a viral rna polymerase w/ their genome before exiting host cell (ex: plant pathogenic reoviruses) reproduction to occurs solely in cytoplasm-w/o use of dna) proteins. Group 4: but is transcribed into a complement that functions as mrna. Must package viral rna-dependent rna polymerase seperated chromosome) (-) strand genome serves as a template to generate rna as well as progeny genome. Some retrovirses (felv) carry oncogenes- can transform into cancer cells transcribed into double stranded dna by enzyme reverse transcriptase (reverse transcriptase is not something we make in our bodies)
