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 ...

If DNA is a book, then how is it read? Learn more about the DNA transcription process, where DNA is converted to RNA, a more portable set of instructions for the cell. The process of transcription ...

In addition to exporting materials out of the nucleus, the protein, called Exportin-1 (also called Xpo1 or Crm1), seems to ...

Single-Molecule Footprinting reveals that RNA polymerase II (Pol II) occupancy is infrequent at mouse promoters. This results ...

In genetics, it has generally been accepted that each gene has one transcription initiation site, located downstream of a core promoter region and typically around a TATA box—a DNA sequence rich ...

Aging cells with weakened gene regulation spuriously transcribe RNAs ... This pattern is normally seen at the start sites of transcription at sequences known as promoters and provides further support ...

The protein that performs transcription binds to the DNA at the promoter, which is typically found directly adjacent to the gene. However, because DNA strands can move and fold, enhancers can ...

New analyses find that divergent transcription, in which one promoter directs the expression of two adjacent ... conserved across all three domains of life. In eukaryotic cells, DNA winds around ...

There is a clear fall off in homology beyond –350 or –400 bp upstream from the start of transcription ... insulin promoters, which is in keeping with the view that most human DNA is not ...

“While mtDNA is much smaller than nuclear DNA, it plays a crucial ... of TEFM resulted in an increase in transcription initiation from the light-strand promoter, as suggested by higher levels ...
