- Control Elements
Control elements are non-coding DNA regions that regular transcription by RNA polymerase II. They come in two forms: enhancers and silencers. Enhancers are a short region of DNA that can bind to proteins called activators. When such binding happens, transcription...

polymerase
Term: polymerase
Origin: An Greek ????/poly(=multiple) +?????/meros(part) -??? /ase(suffix ) meaning that this molecule makes multiple identical parts of a template.
Coined: in 1838 by Swedish chemist Jons Jakob Berzelius (1779-1848)
Definition:
A polymerase is an enzyme that catalyzes the polymerization of nucleic acids such as RNA and DNA which are considered as polymers (polynucleotides).
