Qhov sib txawv tseem ceeb ntawm lentivirus thiab retrovirus yog tias lentivirus yog ib hom kab mob retrovirus thaum retrovirus yog tus kab mob RNA uas muaj cov enzyme reverse transcriptase los hloov RNA genome rau hauv DNA ua ntej nkag mus rau hauv lub cev.
Tsis tas li ntawd, cov kab mob retroviruses yog ib pawg ntawm cov kab mob uas muaj nyob hauv tsev neeg Retroviridae. Hauv tsev neeg no, muaj xya hom: Alpharetrovirus, Betaretrovirus, Gammaretrovirus, Deltaretrovirus, Epsilonretrovirus, Lentivirus thiab Spumavirus. Li no, lentiviruses yog ib hom retroviruses.
Tus kab mob yog dab tsi?
Viruses yog obligate parasites. Txawm hais tias cov kab mob muaj cov noob caj noob ces, lawv tsis muaj ntau yam tseem ceeb ntawm cov kab mob nyob xws li cov qauv ntawm tes thiab kev rov ua dua tshiab. Yog li ntawd, lawv nyob rau hauv qeb tsis nyob. Tib neeg muaj kev txhawj xeeb txog cov kab mob vim lawv cov kab mob tsim tau. Qee qhov piv txwv rau cov kab mob uas ua rau muaj tus kab mob xws li Hepadnavirus, Herpes simplex virus, HIV, Enterovirus, thiab Filoviruses thiab cov kab mob uas lawv ua muaj xws li kab mob siab B (viral), Herpes, AIDS, Polio, thiab Ebola, raws li.
Txhua tus kab mob muaj cov nucleic acid nyob rau hauv lub tsho tiv no protein. Cov khoom no tsis muaj cytoplasm. Cov nucleic acid tam sim no nyob rau hauv cov kab mob tuaj yeem yog DNA lossis RNA, thiab lawv cov genome yog linear lossis ncig; ib leeg-stranded los yog ob-stranded. Ntxiv mus, nyob ntawm lawv qhov sib luag, cov kab mob tuaj yeem yog bihelical, icosahedral, binal, thiab polymorphic. Raws li hom nucleic acid, muaj cov kab mob sib txawv.
Lentivirus yog dab tsi?
Lentivirus yog ib hom kab mob uas los ntawm Tsev Neeg Retroviridae. Nws yog ib hom kab mob retroviruses uas ua rau muaj kab mob ntev thiab tuag taus tshwm sim los ntawm lub sijhawm ntev incubation. Lentivirus yog ib lub hnab ntim cov kab mob uas yog pleomorphic.
Daim duab 01: Lentivirus
Tus kab mob lentivirus muaj ntau yam kab mob uas paub zoo xws li Bovine immunodeficiency virus, Equine infectious anemia virus, Feline immunodeficiency virus, Puma lentivirus, Caprine arthritis encephalitis virus thiab Human immunodeficiency virus 1 (HIV-1).
Retrovirus yog dab tsi?
Retrovirus yog tus kab mob RNA. Txawm li cas los xij, tsis zoo li lwm yam kab mob RNA, retrovirus muaj lub peev xwm tshwj xeeb los thim rov qab nws cov RNA genome mus rau hauv ob-stranded DNA. Nws yog vim qhov enzyme thim rov qab transcriptase muaj nyob rau hauv retroviruses. Tom qab hloov mus rau hauv DNA, tus kab mob DNA sib txuas nrog tus tswv tsev DNA. Yog li, lub peev xwm tshwj xeeb no tau raug siv los tsim qee yam kev siv xws li kev kho noob ntawm cov kab mob uas tau los. Tsis zoo li feem ntau lwm cov kab mob, cov kab mob retrovirus muaj peev xwm kis tau ntau lub hlwb. Vim yog lub peev xwm no, retrovirus tau siv dav hauv kev sim tshuaj thiab tshuaj tiv thaiv kab mob qog noj ntshav. Retroviruses kis mus rau kev faib cov hlwb.
Daim duab 02: Retrovirus
Tsis tas li ntawd, hauv kev sau se ntawm tus kab mob, tus kab mob retrovirus los nyob rau hauv Tsev Neeg Retroviridae, uas suav nrog ob tsev neeg thiab xya genera. Qee qhov piv txwv ntawm retroviruses yog tus kab mob leukemia, HIV-1, nas mammary qog virus, thiab lwm yam.
Dab tsi yog qhov sib txawv ntawm Lentivirus thiab Retrovirus?
- Lentivirus yog hom retrovirus.
- Vim li no, ob qho tib si lentivirus thiab retrovirus yog tus kab mob RNA.
- Ntxiv mus, lawv yog cov kab mob hauv lub hnab.
- Tsis tas li, lawv muaj cov enzyme thim rov qab transcriptase.
- Ob leeg muaj peev xwm hloov RNA genome rau DNA.
- Tsis tas li ntawd, lawv ua rau mob ntev thiab tuag taus rau tib neeg thiab lwm hom tsiaj.
Qhov txawv ntawm Lentivirus thiab Retrovirus yog dab tsi?
Lentivirus yog ib hom kab mob ntawm tsev neeg Retroviridae uas suav nrog cov kab mob retroviruses. Txawm li cas los xij, tus kab mob retrovirus yog tus kab mob RNA uas tuaj yeem hloov nws RNA genome rau hauv DNA. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lentivirus thiab retrovirus. Lentivirus tuaj yeem kis tau cov hlwb tsis sib faib, tsis zoo li lwm cov kab mob retroviruses. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lentivirus thiab retrovirus.
Tsis tas li ntawd, lentivirus muaj ob txoj kev tswj hwm cov noob: tat thiab rev, uas tsis muaj nyob hauv lwm cov kab mob retroviruses. Yog li ntawd, qhov no yog lwm qhov sib txawv ntawm lentivirus thiab retrovirus.
Hauv qab infographic qhia cov ntsiab lus ntawm qhov sib txawv ntawm lentivirus thiab retrovirus.
Summary - Lentivirus vs Retrovirus
Retroviruses yog cov kab mob uas muaj RNA genome. Txawm li cas los xij, tsis zoo li lwm yam kab mob RNA, retroviruses muaj lub peev xwm tshwj xeeb los hloov nws cov RNA genome rau hauv DNA. Thiab, qhov peev xwm no yog vim muaj cov enzyme thim rov qab transcriptase. Lub enzyme hloov RNA rau hauv DNA thiab tom qab ntawd tus kab mob tuaj yeem ua ke cov kab mob DNA mus rau hauv tus tswv tsev genome. Tsis tas li ntawd, retroviruses yog tsev neeg Retroviridae. Hauv tsev neeg no, muaj xya genera ntawm retroviruses. Lentiviruses yog ib lub genus ntawm retroviruses. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm lentivirus thiab retrovirus.
