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 ...

The team also found i-motifs within the "promoter" regions of various genes associated with cancer. Promoters are a type of genetic material that switches a given gene on and off, akin to a light ...

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 ...
