Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kufamba-famba: Upenyu hwehutachiona hwehepatitis B hwakaoma kunzwisisa. Hepatitis B ndeimwe yepararetroviruses shoma dzinozivikanwa: isiri-retroviruses iyo ichiri kushandisa reverse transcription mukugadzira kwayo. Utachiona hunopinda musero nokubatana neNTCP iri pamusoro uye hunobva hwapinda musero. Nemhaka yokuti utachiona hunowanda neRNA inogadzirwa neenzyme inenge iri mumurwere, DNA yejeni yeutachiona inofanira kuendeswa kunonzi nucleus yesero nemapuroteni anenge ari mumurwere anonzi chaperones. DNA yehutachiona ine tambo mbiri inobva yaitwa kuti ive tambo mbiri yakazara nehutachiona hwepolymerase uye inoshandurwa kuita covalently yakavharwa denderedzwa DNA (cccDNA). Iyi cccDNA inoshanda se template yekunyorwa kwemavirusi mana e mRNAs ne host RNA polymerase. Iyo mRNA yakakura, (iyo yakareba kudarika viral genome), inoshandiswa kugadzira makopi matsva egenome uye kugadzira capsid core protein uye viral DNA polymerase. Izvi zvinyorwa zvina zveutachiona zvinowedzera kugadziriswa uye zvinopfuurira kuumba virions yemwana iyo inosunungurwa kubva musero kana kudzokera ku nucleus uye inodzokororwazve kuti ibudise mamwe makopi. Iyo mRNA refu inobva yadzoserwa ku cytoplasm uko virion P protein (DNA polymerase) inogadzira DNA kuburikidza neayo reverse transcriptase chiitiko.  Mubvunzo: Ndeipi vhairasi isiri retroviruses ichiri kushandisa reverse transcription mukugadzirwa kwayo?
