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 ...

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 ...

For the study, Reilly and his colleagues set out to understand how non-coding regions of DNA known as "enhancers" and ...

A new study published in PLOS Genetics has identified an extreme mutational hotspot within the genome of Pseudomonas ...

They also found that the three transcription factors co-occupy genes' promoter regions to regulate each others' activity. To characterize transcriptional regulation in human embryonic stem cells ...

Calculations of homology between the different insulin promoters and the human version ... are in agreement with the opinion that vertebrate genes and immediate upstream flanks are highly ...

Phenotype: Observable expression of a particular gene or genes. Promoter: A segment of DNA sequence that controls initiation of transcription of the gene and is usually located upstream of the gene.

Chinese scientists have uncovered two major genes responsible for sorghum's double-grain spikelet, which dramatically enhance grain number and crop yield. A substantial 35.7-kilobase intrachromosomal ...
