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 ...

There is no discernable significant homology between human and either chicken or zebrafish insulin promoters, which is in keeping with the view that most human DNA is not alignable to species ...

Genes also contain regulatory sequences, such as promoters and enhancers, which control when and where the gene is expressed. These sequences interact with transcription factors and other regulatory ...

A new method for mapping torsion provides insights into the ways that the genome responds to the torsion generated by RNA polymerase II.

And third, the promoter should be insulated from surrounding DNA by including extra DNA before it to further reduce leakiness. We showed that a promoter's performance can be improved more than 100 ...

While previous research had described bidirectional promoters in eukaryotes ... widespread feature conserved across all three domains of life. In eukaryotic cells, DNA winds around histone ... Jack is ...

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 ...

Unexpectedly, they found that this linker histone binds to the promoter of the gene encoding a protein that transports malic acid for storage in apple cells, directly regulating its expression.

The numbers of the principal regulatory elements present in insulin promoters are listed. Given the complexity and uncertainty of predicting the transcriptional outcome of mutations within ...
