Cov ntsiab lus: Kev kho mob cloning , tseem hu ua somatic-cell nuclear hloov chaw, tuaj yeem siv los kho Parkinson tus kab mob hauv cov nas. Hauv kho mob cloning los yog SCNT, lub nucleus ntawm ib tug somatic cell los ntawm ib tug pub kev kawm yog muab tso rau hauv lub qe los ntawm lub nucleus tau raug tshem tawm.
Ib yam li ntawd, nws yog nug, dab tsi yog 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, kev kho mob cloning GCSE yog dab tsi? Kev kho mob cloning . Kev kho mob cloning tuaj yeem tsim cov qia hlwb nrog tib yam tshuaj genetic make-up li tus neeg mob. Cov txheej txheem cuam tshuam nrog kev hloov pauv ntawm cov nucleus los ntawm lub cell ntawm tus neeg mob, mus rau lub qe cell uas nws cov nucleus tau raug tshem tawm. Stem cells uas tsim los ntawm txoj kev no tuaj yeem hloov mus rau tus neeg mob.
Tsuas yog li ntawd, qhov kho mob cloning siv qhov twg?
Lwm yam kev siv ntawm kho mob cloning suav nrog kev kuaj mob ntawm epigenetically ua rau mob qog noj ntshav thiab kev kho mob ntawm kev kho mob siv SCNT, kev tsim tsiaj cov qauv ntawm tib neeg cov kab mob, thiab nws thiaj li tuaj yeem ua rau cov ntaub so ntswg engineering ntawm lub cev de novo.
Dab tsi yog qhov pheej hmoo ntawm kev kho cloning?
Feem ntau qhov tsis zoo ntawm kho mob cloning yog siv embryos. Ntau tus neeg thuam hais tias nws yog kev tuag ntawm tib neeg yog tias embryo siv los rho cov qia hlwb. Lawv suav tias yog kev tua neeg thiab tawm tsam qhov kev ua no nruj me ntsis. Qee tus ntseeg tias kev hloov pauv ntawm somatic cell nuclear kuj yog lub luag haujlwm muab lub neej rau lub embryo.

Ib qho piv txwv ntawm kev sib txawv ntawm tes yog dab tsi?
Cov txheej txheem thiab cov kauj ruam ntawm Cell Differentiation Ib lub xovtooj ntawm tes muaj peev xwm sib txawv rau txhua hom cell hu ua 'totipotent'. Piv txwv ntawm cov qia thiab progenitor hlwb muaj xws li: Hematopoietic Stem Cells - Cov no yog los ntawm cov pob txha pob txha thiab koom nrog hauv kev tsim cov qe ntshav liab thiab dawb nrog rau cov platelets
Ib qho piv txwv ntawm ib qho alloy yog dab tsi?
Ib qho piv txwv ntawm cov hlau yog sib xyaw ntawm cov hlau thiab hlau. Ib qho piv txwv ntawm cov hlau yog cov tin hauv qhov sib xyaw ntawm tooj liab thiab tin uas ua rau tooj liab. Lub alloy yog ib qho fusion ntawm ob lossis ntau dua hlau lossis cov hlau uas tsis yog hlau. Ib qho piv txwv ntawm cov hlau yog tooj dag, uas yog tsim los ntawm tooj liab thiab zinc
Ib qho piv txwv ntawm kev xav hauv kev tshawb fawb yog dab tsi?
Piv txwv ntawm kev tshawb xav txog kev tshawb fawb yog: Issac Newton's "System of the World" uas yog thawj qhov kev xav hauv lub ntsiab ntawm physics. Einstein's Special Relativity thiab General Relativity. Darwin's Theory of Evolution by Natural Selection. Thermodynamics, txoj kev xav uas suav nrog plaub txoj cai ntawm Thermodynamics
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
