Cov txheej txheem ntawm noob caj noob ces engineering mammals yog cov txheej txheem qeeb, tedious, thiab kim. Raws li nrog rau lwm yam hloov caj ces kab mob (GMOs), ua ntej caj ces engineers yuav tsum cais cov noob uas lawv xav mus ntxig rau hauv tus tswv tsev kab mob. Qhov no tuaj yeem raug coj los ntawm ib lub xovtooj ntawm tes uas muaj cov noob lossis cov khoom siv hluavtaws.

Tom qab, lo lus nug yog, dab tsi yog thawj GMO? Cov thawj genetic hloov Cov zaub mov pom zoo rau kev tso tawm yog Flavr Savr txiv lws suav hauv xyoo 1994.

Ib sab saum toj no, cov kws kho mob caj ces ua dab tsi?

Genetic engineering , kuj hu caj ces kev hloov kho los yog caj ces manipulation, yog tus ncaj manipulation ntawm lub cev noob siv biotechnology. Ib yam li ntxig noob , cov txheej txheem tuaj yeem siv los tshem tawm, lossis "knock out", noob . Cov DNA tshiab tuaj yeem muab tso rau hauv qhov chaw, lossis tsom mus rau ib feem ntawm genome.

Salmon hloov pauv hloov pauv li cas?
