<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: Ukudlula: Amanye amagciwane njenge-HIV namagciwane amaningi ezilwane anezimvilophu zegciwane ezimboza amaprotheni azo avikelayo. Ngokuvamile lezi zimvilophu zitholakala ezingxenyeni zamangqamuzana omzimba ama-phospholipid namaprotheni, kodwa zihlanganisa namanye ama-glycoprotein egciwane. Zingase zisize amagciwane ukuba agweme isimiso somzimba sokuzivikela. Ama-glycoprotein asemaphethelweni aleli pheshana akhonza ukukhomba nokunamathisela ezindaweni zokwamukela ku-membrane yomgcini. Ingqikithi yegciwane bese ihlangana ne-membrane yomnikazi, okuvumela i-capsid ne-genome yegciwane ukuba ingene futhi ithelele umnikazi. Umbuzo: Yiziphi izilokazane ezithathelwanayo ezisiza imvilophu?  <response>: amagciwane
