SCNT suav nrog tshem tawm cov nucleus los ntawm lub qe pub, thiab hloov nws nrog DNA los ntawm lub cev txhais tau tias yog cloned . Cov kws tshawb fawb tuaj yeem muaj peev xwm clone lub cev nrog SCNT los ntawm cloning embryos, tshem tawm cov qia hlwb los ntawm blastocyst, thiab txhawb cov qia hlwb kom sib txawv rau hauv qhov xav tau. lub cev.
Tib neeg kuj nug, ua li cas lub cev cloning ua haujlwm?
Cov cloning txheej txheem ua haujlwm los ntawm kev sib txuas tus neeg mob lub cev ntawm tes nrog lub qe tsis muaj qe los ntawm tus neeg pub dawb. Tus neeg mob lub cell ntawm daim tawv nqaij yog muab tso rau hauv daim nyias nyias ntawm lub qe cell thiab chemically induced pib mus rau hauv ib tug blastocyst. Nyob rau hauv lub blastocyst, embryonic hlwb faib, tsim ib pawg ntawm qia hlwb.
Kuj Paub, yog dab tsi kho cloning? Kev txhais lus rau kho mob cloning kho mob cloning . [thĕr'?-pyōō'tĭk] Kev tsim cov embryonic qia hlwb siv los hloov lossis kho cov ntaub so ntswg lossis cov kabmob uas puas lawm, ua tiav los ntawm kev xa cov diploid nucleus los ntawm lub cev cell mus rau hauv lub qe uas nws cov nucleus tau raug tshem tawm.
Ib yam li ntawd, dab tsi yog txhais los ntawm tib neeg cloning?
Tib neeg cloning yog tsim ib daim ntawv genetic zoo tib yam (los yog clone ) ntawm a tib neeg . Cov lub sij hawm feem ntau yog siv los xa mus rau cov khoom siv dag zog tib neeg cloning , uas yog kev tsim tawm ntawm tib neeg cell thiab cov ntaub so ntswg. Nws tsis yog hais txog kev xav thiab kev xa tawm ntawm tus menyuam ntxaib zoo ib yam.
Peb hom cloning yog dab tsi?
Muaj peb hom sib txawv ntawm dag cloning : gene cloning , kev yug me nyuam cloning thiab kho cloning . Gene cloning tsim cov ntawv luam ntawm cov noob lossis ntu ntawm DNA. Kev yug me nyuam cloning tsim cov ntawv luam ntawm tag nrho cov tsiaj.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Dab tsi cov tshuaj tiv thaiv sawv cev rau lub cev qhuav dej synthesis?
Nyob rau hauv lub cev qhuav dej synthesis cov tshuaj tiv thaiv (Daim duab), cov hydrogen ntawm ib tug monomer ua ke nrog cov hydroxyl pawg ntawm lwm monomer, tso ib tug molecule ntawm dej. Nyob rau tib lub sijhawm, cov monomers sib koom electrons thiab tsim covalent bonds. Raws li cov monomers ntxiv koom nrog, cov saw hlau ntawm kev rov ua dua monomers tsim ib lub polymer
Lub npe ntawm lub network loj hauv lub cev yog dab tsi uas tswj cov noob qhia?
NARRATOR: Cov cim npe no thiab lwm tus tswj cov noob qhia los ntawm lub network loj hauv lub cev hu ua epigenome. RANDY JIRTLE: Epigenetics txhais tau tias tsuas yog lub ntsiab lus saum genome
Dab tsi yog qhov tseeb ntawm lub cev lub cev lub cev kev xav xav?
Lub cev lub cev lub ntsiab lus kev xav (PSSH) yog ib txoj hauj lwm hauv lub tswv yim ntawm kev txawj ntse tsim los ntawm Allen Newell thiab Herbert A. 'Ib lub cim lub cev muaj qhov tsim nyog thiab txaus txhais tau tias rau kev ua haujlwm ntse.'
Lub luag haujlwm ntawm lub cev thiab lub cev yog dab tsi?
Anatomy yog kev kawm txog cov qauv thiab kev sib raug zoo ntawm lub cev. Physiology yog kev kawm txog kev ua haujlwm ntawm lub cev thiab lub cev tag nrho
