Een promotor is een specifieke sequentie in het DNA waaraan transcriptiefactorenkunnen binden. Op die manier wordt transcriptie gereguleerd. Een promotor vind je aan het begin van een gen. Als er activerende transcriptiefactoren aan binden, kan RNA-polymerase ook binden en starten met transcriptie. El promotor es una secuencia de ADN necesaria para convertir un gen en activado o desactivado. El proceso de transcripción se inicia en el promotor.

The RNA polymerase(s) RNA is transcribed from DNA using an RNA polymerase (RNAP). DNA fragments containing densely methylated CpGs were enriched using the MBD2B/3L and analyzed with a promoter tiling array. PCA of the DNA methylation signature revealed a clear separation DNA methylation of promoter sequences ensues histone modifications, such as H3K9 methylation and H3/H4 deacetylation, that result in transcriptional gene silencing (TGS) [43,44]. Indeed, when certain criteria are met (see below), plants sprayed with dsRNAs against a promoter sequence may exhibit RdDM and TGS. Promoter and Operator are important DNA sequences that are involved in the transcription process and in transcription regulation.

Promoters are about 100 to 1000 base pairs long and found upstream of their target genes. The sequence of the promoter region controls the binding of the RNA polymerase and transcription factors, therefore promoters play a large role in determining where and when your gene of interest will be expressed. The RNA polymerase (s) DNA fragments containing densely methylated CpGs were enriched using the MBD2B/3L and analyzed with a promoter tiling array. PCA of the DNA methylation signature revealed a clear separation El promotor es una secuencia de ADN necesaria para convertir un gen en activado o desactivado. El proceso de transcripción se inicia en el promotor.

Promotor może mieć długość od kilkudziesięciu do kilkuset nukleotydów. Als Promotor, auch Promoter (ursprünglich franz. promoteur, Anstifter, Initiator), wird in der Genetik eine Nukleotid-Sequenz auf der DNA bezeichnet, die die regulierte Expression eines Gens ermöglicht. Der Promotor ist ein essenzieller Bestandteil eines Gens. Er liegt am 5'-Ende des Gens und somit vor dem RNA -kodierenden Bereich.
