Nyob rau hauv thaj chaw ntawm molecular biology, ib tug corepressor yog ib tug molecule uas represses qhov kev qhia ntawm noob. … Tus repressor nyob rau hauv lem khi rau ib tug gene tus neeg teb xov tooj ib ntus (nqe ntawm DNA uas ib tug transcription factor khi rau tswj gene qhia), yog li thaiv transcription ntawm cov noob.
Lub luag haujlwm ntawm corepressor yog dab tsi?
Corepressor complexes yog muaj ntau yam proteins uas ua haujlwm hauv transcriptional silencing lossis repression, suav nrog DNA-binding proteins, histone methyltransferases, HDACs, thiab chromatin structural Cheebtsam (saib xyuas hauv Schoch thiab Abel, 2014).
Corepressor hauv operon yog dab tsi?
A me me zoo li trytophan, uas hloov lub zog rau hauv nws lub xeev nquag, hu ua corepressor. … Tus trp repressor nrog lub khi tryptophan txuas rau tus neeg teb xov tooj, thaiv RNA polymerase los ntawm kev khi rau tus txhawb nqa thiab tiv thaiv kev hloov pauv ntawm operon.
corepressor molecule quizlet yog dab tsi?
corepressor. A me me molecule uas khi rau cov kab mob tua kab mob protein thiab hloov nws cov duab, tso cai rau nws hloov qhov operon tawm. inducer.
Dab tsi yog qhov txawv ntawm kev tawm tsam thiab corepressor?
Qhov sib txawv tseem ceeb ntawm kev tawm tsam thiab corepressor yog repressor protein ncaj qha khi rau tus neeg teb xov tooj ntawm cov noob thiab inhibits gene qhiathaum corepressor proteinkhi rau cov protein repressor thiab indirectly tswj cov noob qhia.
