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 ...

Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of ...

Finding the beginning of genes within genomic sequence presents a formidable challenge to projects to annotate the human genome sequence. In the Advanced Online Publication of Nature Genetics Ramana ...

Calculations of homology between the different insulin promoters and the human version were carried out across the region spanning –600 to +1. The downstream 100 bp, which contains two cyclic ...

New analyses find that divergent transcription, in which one promoter directs the expression of two adjacent genes oriented in opposite directions, is conserved across all domains of life. Jack is a ...

Researchers have engineered yeast to efficiently convert methanol into D-lactic acid, a key compound for biodegradable plastics and pharmaceuticals. By optimizing gene and promoter combinations, they ...

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 ...
