Thaum tsis muaj lactose, tus lac repressor khi nruj rau tus neeg teb xov tooj. Nws tau txais hauv RNA polymerase txoj kev, tiv thaiv kev hloov pauv. Hauv qab vaj huam sib luag: Nrog lactose. Allolactose (rearranged lactose) khi rau lac repressor thiab ua rau nws tso tawm ntawm tus neeg teb xov tooj.
Yuav ua li cas rau kev sau ntawv ntawm lac operon thiab thaum lactose tsis tuaj?
Thaum tsis muaj lactose, lac operon raug kaw. Qhov no yog vim hais tias ib tug repressor protein yog tsim uas khi rau tus neeg teb xov tooj cheeb tsam. Qhov no tiv thaiv RNA polymerase los ntawm kev khi rau operon thiab yog li tiv thaiv kev hloov pauv ntawm cov noob caj noob ces.
Kev muaj lossis tsis muaj lactose cuam tshuam li cas rau lac operon quizlet?
lactose hloov mus rau allolactose, uas inhibits lac repressor. CAP tsis pab RNA polymerase binding thiab transcription raug muab tua. Cov piam thaj qis thiab muaj lactose.
Thaum tsis muaj lactose, tus neeg tawm tsam induces transcription ntawm lac operon?
Peb lub hom phiaj tsim nyog uas yuav tsum tau ua kom txo qis lactose hauv E. coli yog nyob ib sab ntawm ib leeg hauv lac operon. Thaum tsis muaj lactose, repressor protein khi rau tus neeg teb xov tooj, lub cev thaiv RNA polymerase los ntawm kev sau cov noob caj noob ces.
Qhov twg ntawm lac operon puas muaj cov tshuaj tiv thaiv kab mob thaum tsis muaj lactose?
Qhov no ua rau muaj kev nkag siab zoo rau lub xovtooj ntawm tes vim tias nws yuav muaj lub zog khib nyiab los tsim cov enzymes los ua cov lactose yog tias tsis muaj lactose. Thaum tsis muaj lactose, lub lac repressor yog khi rau thaj tsam tus neeg teb xov tooj ntawm lac operon, lub cev tiv thaiv RNA polymerase los ntawm kev sau cov noob caj ces.
