Recombinant DNA yog ib lub tshuab cov kws tshawb fawb tsim tawm uas ua rau nws ua tau ntxig a noob neej nyob rau hauv cov caj ces khoom ntawm ib qho kab mob . Qhov "recombinant" micro-organism tam sim no tuaj yeem tsim cov protein nkag los ntawm noob neej . Cov kws tshawb fawb tsim lub tib neeg cov insulin insulin hauv lub chaw kuaj mob.
Tsis tas li, koj yuav tso cov noob insulin rau qhov twg thiab vim li cas?
Tib neeg noob insulin yog tso rau hauv txhua plasmid. Plasmid ua raws li vector - nws yog siv los hloov DNA los ntawm ib yam kabmob mus rau lwm qhov. Cov kab mob tua kab mob tau tsim los txhawm rau hloov pauv cov noob caj noob ces. Cov kab mob ntawm cov kab mob uas ua tiav plasmids tau piav qhia tias tau hloov pauv.
Tsis tas li, yam tshuaj twg uas kws tshawb fawb tau tsim los siv cov kab mob los tsim cov tshuaj insulin? Genentech muaj kev txawj ntse rau ua tib neeg hluavtaws cov tshuaj insulin -hauv chaw kuaj mob, los ntawm kab mob , siv lawv tsis ntev los no-pov thawj recombinant DNA thev naus laus zis.
Raws li, vim li cas thiaj siv cov kab mob hauv kev tsim tshuaj lom neeg?
Kab mob cell tuaj yeem yog noob neej hloov kho kom lawv muaj noob los tsim cov tshuaj insulin rau tib neeg. Raws li cov kev hloov kho no kab mob loj hlob, lawv tsim tib neeg cov insulin. Cov protein no tuaj yeem ua kom huv thiab muab rau cov neeg mob ntshav qab zib.
Lub luag haujlwm ntawm tib neeg cov tshuaj insulin yog dab tsi?
Pancreatic islet -cells tswj tus nqi ntawm noob insulin transcription nyob rau hauv kev teb rau ib tug xov tooj ntawm cov as -ham, lub zog tshaj plaws uas yog qabzib. Txhawm rau ntsuas nws cov kev cai los ntawm cov piam thaj, tus neeg txhawb nqa ib qib zuj zus raug cais los ntawm noob neej insulin.

Vim li cas cov kws tshawb fawb tshawb fawb txog kab mob?
Cov kab mob tsis yog tsuas yog muaj ntau, ntau yam, thiab tseem ceeb rau kev nyab xeeb, lawv ua lub luag haujlwm tseem ceeb hauv kev hloov pauv ntawm lawv cov tswv. Ntxiv rau qhov xaiv qhov siab uas lawv ua rau cov pej xeem ntawm tes, raws li tau hais los saum no, lawv txhawb kev hloov pauv ntawm cov noob thiab cov genomes thiab sib sau cov noob nyob thoob plaws ib leeg
Dab tsi yog kev tshawb fawb kws tshawb fawb txog keeb kwm keeb kwm los kwv yees lub sijhawm tuag piav qhia vim li cas kev kwv yees tsis tas yuav ncaj?
Ib tus kws tshawb fawb kws tshawb fawb txog keeb kwm tshawb fawb kev txhim kho kab ntawm kab hauv lub cev los kwv yees lub sijhawm tuag. Cov kev txiav txim siab no tsis yog qhov yooj yim ib txwm vim tias tus nqi ntawm cov kab menyuam loj hlob tau cuam tshuam los ntawm ib puag ncig cuam tshuam xws li thaj chaw nyob, huab cua, thiab huab cua puag ncig
Vim li cas nws thiaj tseem ceeb rau tus kws saib xyuas neeg mob saib xyuas cov phaj thiab cov tais zaub mov thaum cov neeg nyob hauv tau noj mov tas lawm?
Vim li cas nws thiaj tseem ceeb rau tus kws saib xyuas neeg mob saib xyuas cov phaj thiab cov tais zaub mov thaum cov neeg nyob hauv tau noj mov tas lawm? Nws pab txheeb xyuas qhov kev hloov pauv ntawm cov neeg nyob hauv kev nyiam zaub mov. Tus kws saib xyuas mob nkeeg yuav tsum txheeb xyuas cov zaub mov thiab dej ua ntej cov neeg nyob hauv
Puas yog cov kws tshawb fawb feem ntau siv rau kab mob arboviruses?
Rau arboviruses, vectors feem ntau yog yoov tshaj cum, zuam, sandflies thiab lwm yam arthropods uas haus cov ntshav ntawm vertebrates rau kev noj haus lossis kev loj hlob
Cov kab mob dab tsi ua rau cov kws kho mob tshawb fawb?
Molecular pathology feem ntau siv hauv kev kuaj mob qog noj ntshav thiab kab mob sib kis. Molecular Pathology feem ntau yog siv los tshuaj xyuas cov qog nqaij hlav xws li melanoma, brainstem glioma, qog hlwb thiab ntau lwm hom qog noj ntshav thiab kab mob sib kis
