Mutations that disrupt the trpR gene lead to elevated production ... can once again bind to the operator/promoter, quickly turning off expression of the operon, returning expression to basal ...

The answers to such questions lie in the study of gene expression. Thus ... bind near the start of mRNA production for an entire operon, or cluster of coregulated genes. Furthermore, some ...

DNA sequences that regulate expression of the insulin gene are located within a region spanning ~400 bp that flank the transcription start site. This region, the insulin promoter, contains a ...

The transcription factor PDX-1 emerges as one of the fundamental regulators of insulin expression for several reasons: all promoters have at least one A box with A3 being the most conserved ...
