Promoter (genetics) - Wikipedia

(9 days ago) In genetics, a promoter is a sequence of DNA to which proteins bind that initiate transcription of a single RNA from the DNA downstream of it. This RNA may encode a protein, or can have a function in and of itself, such as tRNA, mRNA, or rRNA.Promoters are located near the transcription start sites of genes, upstream on the DNA (towards the 5' region of the sense strand).

FAQ?

Where are the promoter and operator sequences located?

Promoter and Operator are important DNA sequences that are involved in the transcription process and in transcription regulation. Promoter sequences are found in both prokaryotes and eukaryote. Promoter is the site for binding of RNA polymerase.

What is the relationship between promoter sequence and its strength?

Relationship between promoter sequence and its strength in gene expression. Promoter strength, or activity, is important in genetic engineering and synthetic biology. A constitutive promoter with a certain strength for one given RNA can often be reused for other RNAs.

What is the role of a gene promoter?

Gene promoters are the ignition system of genes and harbor regions of DNA (cis-acting elements) that provide binding sites for mostly nuclear proteins (transcription factors) that enhance or suppress transcriptional activation. A gene promoter is the genomic DNA sequence immediately upstream of the transcription start site.

Where are the consensus sequences located in the promoter?

Two promoter consensus sequences are at the -10 and -35 regions upstream of the initiation site. The σ subunit of RNA polymerase recognizes and binds the -35 region. Five subunits (α, α, β, β’, and σ) make up the complete RNA polymerase holoenzyme. promoter: the section of DNA that controls the initiation of RNA transcription
