Summary of Different Virus Types BacteriophageAnimal Virus T4 ( Lytic Cycle)Lambda (Lysogenic and lytic cycle) fluhuman immunodeficiency virus Overall social structure Complex structure with head, contractile cut across assemblage (surrounded by tail guinea pig) and base plate with connect coherent tail fibers 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 scrape up glycoprotein gp120 and trans membrane glycoprotein gp 40 Viral Genome Consist of a analog double-stranded desoxyribonucleic acid genome (dsdesoxyribonucleic acid genome), creation injected into the force cells during penetrationConsist of a linear double-stranded DNA genome (dsDNA genome)Comprises 8 distinct linear segments of ssRNA (-)HIV-1 genome comprises 2 identical copies of ssRNA(+) book of account form of capsi dicosahedralicosahedralhelicalconical HostEscherichia coli bacteriumEscherichia coli bacteriaHuman respiratory epithelial cellsCells that express the CD4 sensory sense organ on the membrane. E.g. T helper cells Attachment Bind to terminate particular receptor sites -Tail fibre bind to complementary peculiar(prenominal) receptor sites on host cell moleHemagglutinin binds to specific glycoprotein receptorsGlycoprotein 120 binds specifically CD4, leads to the fusion of the HIV envelope to the host cell membrane Reproductive Cycle 1. Penetration -Tail fibres anchor baseplate pins to the cell outdoors -Tail sheath contracts and tail lysozyme degrade cell wall and membrane -Phage dsDNA is injected into the bacterial cytoplasm, leaving the empty capsid right(prenominal) -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 bloodsucki ng RNA polymerase-Fusion of the HIV envelope! with the hosr cell membrane releases nucleocapsid -Capsid disruptive by cellular enzymes, releasing the...If you want to get a full essay, stray it on our website: OrderEssay.net
