Qhov Tseem Ceeb Qhov Sib Txawv - Genetic Engineering vs Genetic Modification
Kev tsim kho caj ces thiab kev hloov kho caj ces yog ob nqe lus zoo sib xws, txawm hais tias lawv tuaj yeem sib txawv raws li lawv daim ntawv thov. Ob lo lus no tau siv dav hauv kev ua liaj ua teb biotechnology thiab cog qoob loo technologies. Genetic engineering yog hais txog cov txheej txheem uas cov nroj tsuag lossis cov kab mob hauv cov kab mob caj ces raug hloov kho raws li qhov tshwj xeeb. Yog li, nyob rau hauv cov kab mob uas tsim los ntawm cov kab mob, cov yam ntxwv qhia los ntawm cov txheej txheem DNA thev naus laus zis tau paub ua ntej nws tau qhia. Kev hloov kho caj ces yog cov txheej txheem uas cov noob caj noob ces hloov los ntawm ntau txoj hauv kev thiaj li ua tiav qhov kev xav tau. Qhov no tuaj yeem yog qhov tshwm sim ntuj thiab siv dav hauv kev cog qoob loo. Qhov sib txawv tseem ceeb ntawm Genetic engineering thiab Genetic Modification yog nws cov txheej txheem. Thaum lub sij hawm genetic engineering, cov noob uas muaj cov yam ntxwv uas xav tau yog nkag mus rau hauv lub cev los ntawm kev sib txuas DNA thev naus laus zis. Thaum lub sij hawm hloov kho caj ces, cov kab mob tau hloov kho los ntawm ntau txoj hauv kev kom tau txais qhov xav tau zoo.
Dab tsi yog Genetic Engineering?
Genetic engineering yog txheej txheem tsim khoom tsim nyog, qhov twg cov kab mob hauv cov caj ces yog hloov kho los ntawm kev siv thev naus laus zis DNA. Thaum lub sij hawm genetic engineering txheej txheem, cov noob tau qhia los hloov cov noob caj noob ces yog paub. Cov noob ntawm kev txaus siab yog cloned rau ib tug sib haum vector. Vectors tuaj yeem yog plasmids xws li pBR322, Ti plasmid ntawm Agrobacterium tumerfaciens lossis cov kab mob xws li Tobacco Mosaic Virus thiab Cauliflower Mosaic virus thiab lwm yam. Gene transformation method such as electroporation, biolistic gene gun method thiab PEG-mediated gene transfer is also used to introduce the Foreign DNA. mus rau tus tswv tsev lub cev.
Thaum ua tiav cov txheej txheem hloov pauv, cov hloov pauv thiab cov tsis hloov pauv lossis cov nroj tsuag raug xaiv siv cov txheej txheem tshwj xeeb xws li GUS kev soj ntsuam. Los ntawm txoj kev no, cov kab mob tsim los yog cov nroj tsuag tau tsim.
Cov kab mob thiab cov nroj tsuag tau tsim cov noob caj noob ces yog qhov tseem ceeb rau kev lag luam. Cov kab mob lossis cov nroj tsuag muaj peev xwm tsim tau cov khoom sib txawv xws li amino acids, proteins, vitamins thiab tshuaj tua kab mob yog tsim los ntawm genetic engineering. Tsis tas li ntawd, Genetically engineered kab mob kuj siv los ua zaub mov xws li tshuaj tua kab mob rau txiv lws suav, thiab lwm yam.
Daim duab 01: Genetic Engineering
Txawm hais tias cov khoom noj khoom haus tau tsim kho caj ces yuav yog txoj hauv kev zoo rau kev xav tau khoom noj khoom haus thoob ntiaj teb thiab cov pej xeem nce, genetic engineering ntawm cov qoob loo lossis cov kab mob yog ib qho kev txhawj xeeb ntau thiab muaj ntau yam kev txhawj xeeb txog kev sib raug zoo thiab kev coj ncaj ncees uas tau sib cav. thoob plaws lub zej zog scientific.
Kev hloov pauv caj ces yog dab tsi?
Kev Hloov Kho Cuam Tshuam yog cov lus dav dav uas muaj ntau yam txheej txheem koom nrog hauv kev qhia txog kev hloov kho rau cov kab mob lossis cov nroj tsuag nyob rau ntau tiam neeg. Kev hloov pauv caj ces tau siv los ntawm cov neeg ua liaj ua teb thiab cov cog qoob loo rau ntau pua xyoo. Kev hloov pauv caj ces cuam tshuam los hloov pauv cov tswv cuab 'cov caj ces los ntawm kev qhia cov txheej txheem sib txawv rau tus tswv tsev uas yuav ua rau muaj kev hloov pauv tshiab.
Genetic engineering yog ib hom kev hloov kho caj ces. Kev hloov pauv caj ces cuam tshuam nrog kev sib koom ua ke ntawm gametes, thiab kev hloov kho tau dhau los ntawm ib tiam mus rau lwm tiam. Qee yam kev hloov kho caj ces ntawm cov nroj tsuag muaj xws li hybridization, xaiv thiab induced mutation. Hauv kev cog qoob loo, hla cov kab mob-tiv taus ntau yam nrog cov kab mob cuam tshuam ntau yam dhau ob peb tiam neeg yuav kawg tsim cov kab mob-resistant ntau yam. Cov tswv yim cog qoob loo siv txij li ntau txhiab xyoo yog ib qho piv txwv classic ntawm kev tau txais cov khoom noj hloov pauv.
Kev hloov pauv caj ces tuaj yeem tshwm sim hauv ib puag ncig ntuj thiab tuaj yeem tshwm sim hauv cov xwm txheej ntuj. Yog li ntawd, nws yog kiag li tsis dag los yog nyob rau hauv vitro. Thaum lub sij hawm hloov caj ces, recombinant DNA technology molecular biological txoj kev tsis koom nrog.
Daim duab 02: Kev hloov pauv caj ces ntawm tus kab mob
Yog li, ntau xyoo ntawm cov khoom noj uas tus txiv neej noj yog cov zaub mov hloov pauv. Cov txheej txheem ntawm kev hloov kho caj ces tsis tuaj yeem raug tso tseg vim nws tseem cuam tshuam nrog lub hauv paus ntsiab lus ntawm kev muaj sia nyob ntawm qhov fittest. Ntau tiam neeg, kev hloov pauv hauv cov nroj tsuag lossis kab mob tau ua rau lawv muaj sia nyob thaum tsis ua rau muaj kev phom sij rau ib leeg.
