Summary of Different computer virus Types BacteriophageAnimal Virus T4 ( Lytic Cycle)Lambda (Lysogenic and lytic cycle) fluhuman immunodeficiency virus Overall Structure Byzantine grammatical construction with head, contractile burn down across assembly (surrounded by groundwork guinea pig) and mean(a) plate with attached rational lav eccentrics and baseplate pins Complex structure with head, non-contractile tail (surrounded by tail sheath) and 1 tail fiber Enveloped virus with glycoprotein hemagglutinin (HA) and enzyme neuraminidase (NA) spikes Enveloped retrovirus with surface glycoprotein gp great hundred and transmembrane glycoprotein gp 40 Viral Genome Consist of a running(a) double-stranded desoxyribonucleic acid genome (dsDNA genome), institution injected into the force cubicles during penetrationConsist of a linear double-stranded DNA genome (dsDNA genome)Comprises 8 limpid linear segments of ssribonucleic acid (-)HIV-1 genome comprises 2 indistinguishable copies of ssRNA(+) word form of capsidicosahedralicosahedralhelicalconical HostEscherichia coli bacteriumEscherichia coli bacteriaHuman respiratory epithelial jail boothsCells that express the CD4 sensory(a) sensory receptor on the membrane. E.g.
T helper cells Attachment have got to completing particular receptor sites -Tail fibre bind to complemental peculiar(prenominal) receptor sites on server cell wallHemagglutinin binds to specific glycoprotein receptorsGlycoprotein 120 binds specifically CD4, leads to the fusion of the HIV windbag to the host cell membrane Reproductive Cycle 1. Penetration -Tail fibres grit baseplate pins to the cell surface -Tail sheath contracts and tail lysozyme degrade cell wall and membrane -Phage dsDNA is injected into the bacterial cytoplasm, exit the empty capsid outside -Viral envelope fuses with membrane of the endocytic vesicle, nucleocapsid released into the cytoplasm -Capsid vitiated by cellular enzymes, releasing ssRNA(-) genome segments and viral RNA bloodsucking RNA polymerase-Fusion of the HIV envelope with the hosr cell membrane releases nucleocapsid -Capsid disruptive by cellular enzymes, releasing the...If you motivation to get a encompassing essay, order it on our website:
