<prompt> Bheka isigaba esingezansi bese uphendula umbuzo ngemuva kwalokho ngolimi olufanayo nesigaba: Isigaba: Amanye amagciwane isib. i-HIV kanye namagciwane amaningi ezilwane anezimvilophu zegciwane ezihlanganisa amaprotheni azo okuvikela i-capsid. Imvilophu ngokuvamile zivela ezingxenyeni zezingqimba zamaseli omnikazi ama-phospholipids namaprotheni, kodwa zifaka amanye ama-glycoprotein egciwane. Bangasiza amagciwane ukuba agweme amasosha omzimba omnikazi. Ama-glycoprotein asendaweni yemvilophu asebenza ukubopha nokuhlonza izindawo zokwamukela ku-membrane yomnikazi. Imvilophu yegciwane bese ihlangana ne-membrane yomnikazi, ivumela i-capsid ne-genome yegciwane ukungena nokuthelela umnikazi. Umbuzo: Yimaphi ama-envelopes asiza ama-agent athathelanayo?  <response>: amagciwane
