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

Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins. Promoter sequences are typically located directly upstream or at the 5' end of the ...

DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...

In addition, regulatory sites on prokaryotic DNA are typically located close to transcription promoter sites — and this plays an important part in gene expression. For an example of how this ...

A new study has unveiled the genetic mechanism controlling citric acid content in jujube fruit, identifying a natural ...

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 ...

[101] This sequence, which is known to induce DNA curvature, may serve to bring together proteins that bind at sites flanking this motif. Examination of the other insulin promoters reveals that ...
