How Is Gene Expression Regulated ... Activator proteins bind to regulatory sites on DNA nearby to promoter regions that act as on/off switches. This binding facilitates RNA polymerase activity ...

The transcription of a gene is controlled by a so-called promoter region, which is located directly before the start of the gene. More detailed investigations in recent years have indicated that ...

Engineers and biologists at Dartmouth College have found that, just like word order affects meaning in a sentence, the ...

The numbers of the principal regulatory elements present in insulin promoters are listed ... in the table because the immediate downstream region shares 98% identity with the human and all ...

On the other hand, invertebrate animals generally have a "mosaic" pattern of methylation, where regions of ... role in repressing gene expression, perhaps by blocking the promoters at which ...

Farr, Christina Vasileiou, Peter A. Lind, and Paul B. Rainey, reveals that mutations in the promoter region of the rpoS gene occur at an astonishing rate—approximately 5,000 times higher than ...
