Uyini umgomo we-mRNA?
Uyini umgomo we-mRNA Umuthi wokugoma we-mRNA udlulisela i-RNA kumaseli omzimba ukuze uveze futhi ukhiqize ama-antigen amaprotheni ngemva kokuguqulwa okufanelekile kwe-in vitro, ngaleyo ndlela kuholele umzimba ukuthi ukhiqize impendulo yokuzivikela komzimba ngokumelene ne-antigen, ngaleyo ndlela andise i-bod...Funda kabanzi -
Ubuchwepheshe be-PCR
I-PCR (i-polymerase chain reaction) ingenye ye-in-vitro DNA amplification technologies, enomlando ongaphezu kweminyaka engama-30.Ubuchwepheshe be-PCR basungulwa ngu-Kary Mullis wase-Cetus, e-USA ngo-1983. U-Mullis wafaka isicelo se-PCR patent ngo-1985 futhi washicilela iphepha lokuqala lezemfundo le-PCR leSayensi ngokufanayo...Funda kabanzi -

Ungakuthuthukisa kanjani ukusebenza kahle kokubhalwe phansi kwe-LncRNA?
I-Lead Long non-coding RNA, i-lncRNA iyi-RNA engafaki amakhodi enobude obungaphezu kwama-nucleotide angu-200, ngokuvamile phakathi kuka-200-100000 nt.I-lncRNA ilawula ukuvezwa kofuzo emazingeni e-epigenetic, okulotshiweyo kanye nangemuva kokuloba, futhi ibamba iqhaza ekuthuliseni i-X chromosome, ukuphrinta kwe-genome kanye ne-chroma...Funda kabanzi -
Ingadluliswa isuka kumuntu iye komunye ngemizuzwana eyi-14.Kwenzekeni kuhlobo “oluthathelana kakhulu” lweDelta eZhong Nanshan Pass?
Umthombo ohumushiwe: Umhleli wethimba le-WuXi AppTec E-Guangzhou, e-China, amaphoyisa anesibopho sokusiza uphenyo lwesifo esiwumshayabhuqe akhiphe ividiyo egadayo: Endaweni yokudlela efanayo, laba ababili bangena endlini yokugezela belandelana ngaphandle kokuthintana ngokomzimba.Imizuzwana engu-14 kuphela ye-co-e...Funda kabanzi -
Ukulebula kwamangqamuzana e-SNP nokutholwa
Ngemva kokuba isazi saseMelika u-Eric S. Lander ehlongoza ngokusemthethweni i-nucleotide polymorphism (SNP) njengemaki yamangqamuzana esizukulwane sesithathu ngo-1996, i-SNP iye yasetshenziswa kabanzi ekuhlaziyeni isimilo sesimo sezomnotho, ukwakhiwa kwemephu yokuxhumanisa izakhi zofuzo, kanye nokuhlolwa kwezakhi zofuzo zabantu., D...Funda kabanzi -
Isayensi Edumile |Ungayithola kanjani i-coronavirus entsha nge-qPCR
I-COVID-19 isifo esithathelwanayo esibangelwa i-Severe Acute Respiratory Syndrome Coronavirus Type 2. Uma umuntu ethelelekile, izimpawu ezivame kakhulu zihlanganisa imfiva, ukukhwehlela, nokuphefumula.Amasampula asetshenziselwa ukuhlolwa angaqoqwa ngama-nasopharyngeal swabs noma ama-oropharyngeal swabs.Yini mina...Funda kabanzi -
Ukuhlaziywa okugcwele kobuchwepheshe bokuxilonga amangqamuzana (1)
Ubuchwepheshe bokuxilongwa kwamangqamuzana busebenzisa izindlela zebhayoloji yamangqamuzana ukuthola ukuvezwa nokwakheka kwezakhi zofuzo zomzimba womuntu kanye namagciwane ahlukahlukene, ukuze kufezwe inhloso yokubikezela nokuxilonga izifo.Eminyakeni yamuva nje, ngokuthuthukiswa nokuvuselelwa kwamangqamuzana ...Funda kabanzi -
Ukufunda Okubalulekile丨44 amaphuzu wokuqapha ubungozi elabhorethri ye-PCR
Kunezinhlobo ezimbili eziyinhloko zobungozi kulabhorethri ye-PCR: ubungozi be-biosafety kanye nobungozi bokungcoliswa kwe-nucleic acid.Okwangaphambili kulimaza abantu kanye nemvelo, futhi lokhu kwakamuva kuthinta imiphumela yokuhlolwa kwe-PCR.Le ndatshana imayelana nezindawo zokuqapha ubungozi zelabhorethri ye-PCR kanye nelev yobungozi ehambisanayo...Funda kabanzi -
Ngemva kokugonywa ngomgomo we-COVID-19, ngazi kanjani ukuthi amasosha omzimba akhiqiziwe?
Kuze kube nguJuni 25, 2021, Ikhomishini Yezempilo Kazwelonke YaseChina ikhiphe imininingwane ekhombisa ukuthi bangaphezu kwezigidi ezingama-630 abantu abagonyiwe ezweni lami, okusho ukuthi izinga lokugoma labantu bonke eChina selidlule ama-40%, okuyisinyathelo esibalulekile ekusunguleni umhlambi ...Funda kabanzi -
Ngingakwazi Ukuhlolela I-Coronavirus Ekhaya?
