a nucleotide sequence that increases the rate of genetic transcription by preferentially increasing the activity of the nearest promoter on the same DNA molecule
{i} improver, strengthener, intensifier (of taste or odor); (Biology) segment of DNA that is found near a gene and increases the appearance of the gene's visible phenotypes
One of the necessary regulatory elements of a gene An enhancer is a site on DNA to which a complex of transcription factors bind to affect the availability of the promoter to RNA polymerase A gene may have multiple enhancers
A cis-regulatory sequence that can elevate levels of transcription from an adjacent promoter Many tissue specific enhancers can determine spatial patterns of gene expression in higher eukaryotes Enhancers can act on promoters over many tens of kilobases of DNA and can be 5' or 3' to the promoter they regulate A eukaryotic DNA sequence that increases transcription of a region even if the enhancer is distant from the region being transcribed
A cis- acting sequence that increases the utilization of (some) eukaryotic promoters, and can function in either orientation and in any location (upstream or downstream) relative to the promoter Eukaryotes and eukaryotic viruses [DDBJ/ EMBL/ GenBank Feature Table] http: //www ebi ac uk/embl/Documentation/FT_definitions/feature_table html
