Five of these are core subunits which form crab claw shapes with DNA at their centres, channels for RNA products and NTP substrates as well as an additional 5 units. The claw like shape stabilizes ...

For instance, bacteria contain a single type of RNA polymerase, while eukaryotes (multicellular organisms and yeasts) contain three distinct types. In spite of these differences, there are ...

The prokaryotic form of RNA polymerase has four subunits capable of transcribing all types of RNA. In eukaryotes, these enzymes have eight or more subunits that facilitate the attachment and ...

During transcription initiation, a large, multi-molecular machinery assembles on the promoter of a gene, to enable proper positioning of the RNA Polymerase enzyme and commence accurate mRNA synthesis.

The synthesis usually requires one or more enzymes like RNA polymerase. The DNA strand ... For example, a poly and a 5' cap are added to eukaryotic pre-mRNA and introns are removed by the spliceosome.

In the latest shake-up for scientific dogma, research has demonstrated that eukaryotic cells can convert RNA sequences back into DNA, through a misunderstood, ‘error-prone’ polymerase. Historically, ...

Despite polα–primase being the first human polymerase discovered, the way it synthesizes very specific lengths of RNA and DNA in a single strand remained unclear for more than 50 years.

Researchers show that polymerase theta can efficiently convert RNA sequences back into DNA, a feat more common in viruses than eukaryotic cells. Editor's Note: Thomas Jefferson University issued ...

This time, they uncovered the first programmable RNA-guided system in eukaryotes. Just a few months ago, the Zhang lab adapted a contractile injection system, found naturally in bacteria ...
