The lac operon yog an operon, lossis pab pawg ntawm cov noob nrog ib tus neeg txhawb nqa (tau sau ua ib qho mRNA). Cov noob nyob rau hauv operon encode proteins uas tso cai rau cov kab mob siv lactose los ua lub zog.
Vim li cas lac operon yog noob?
Tus duo tau sau tseg tias lac operon muaj peb lub noob uas encode proteins koom nrog hauv lactose metabolism Cov no yog hu ua lac z, lac y, thiab lac a. Lub lac z gene encodes beta-galactosidase, lub lac y noob encodes ib permease, thiab cov lac a gene encodes transacetylase enzyme.
lac operon piv txwv ntawm yog dab tsi?
Lub lac operon yog cov piv txwv classical ntawm an inducible circuit uas encodes cov noob rau kev thauj cov lactose sab nraud rau hauv lub cell thiab nws hloov mus rau qabzib thiab galactose.
Yuav ua li cas muaj lac operon?
Yuav tsum tau thauj thiab metabolism ntawm lactose hauv Escherichia Coli (E. coli). Lub lactose operon los yog lac operon muaj peb hom kab ke xws li lacZ, lacY, thiab lacA uas encode proteins koom nrog hauv lactose metabolism nrog rau ntau yam kev tswj hwm noob..
Puas yog operon thiab lac operon tib yam?
Lactose operon (lac operon) yog operon xav tau rau kev thauj thiab metabolism ntawm lactose hauv E. coli thiab ntau lwm cov kab mob enteric.
