(Penn State) By capturing the crystal structure of RNA polymerase during a nontraditional form of transcription -- reiterative transcription -- researchers have identified a new pathway used by RNA to exit an enzyme.

Polymerase Chain Reaction (PCR)
PCR (Polymerase Chain Reaction) uses the ability of DNA polymerase (enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two ident...
Enzymes are proteins that catalyze (i.e., increase the rates of) chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical re...
