Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists ...
Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases. (Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base ...
This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...
Nucleosomes are barriers to RNA Polymerase II (Pol II) transcribing along gene bodies in eukaryotes. We found that a fragile “tailless nucleosome” could be generated to resolve the Pol II pausing ...
