RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. As complex molecule composed of protein subunits, RNA ...

Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. However, this is where the similarities between prokaryote and eukaryote expression end. Central to the ...

Ribosomes are composed of two subunits, the small and large subunits ... This discovery led to the concept of the ribosome as a ribozyme, an RNA molecule with enzymatic properties. The catalytic ...

Trypanosomes are parasites that cause sleeping sickness, Chagas disease, and various animal diseases. Diagnosis and treatment remain complex and no effective vaccine has been developed. A better ...

Further investigation into SNORA13 revealed that it modifies RNA bases in the ribosome’s active site ... they isolated and centrifuged the ribosomes to separate their small and large subunits. Mendell ...

It was discovered 50 years ago that chloroplasts contain their own unique RNA polymerase. Since then, scientists have been ...

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries the information contained within DNA to the ribosomes, where the genetic information is synthesized into ...
