DNA transcription is the vital first step needed for switching on our genes. For a gene to be switched on, it must be acted ...

This active repressor can bind to a region near the promoter called an operator (yellow ... In multicellular organisms, nearly all cells have the same DNA, but different cell types express ...

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 ...

a 770,000-base length of DNA on chromosome 6, which has a promoter and three enhancer regions and is known to undergo transcriptional bursting in cultured mouse embryonic stem cells. The ...

The flanking regions share no homology ... G2 motifs may indicate that G2-facilitated DNA bending abets interactions between proteins binding to the promoter. The G2 motif is absent from the ...
