... certain basic functions. Each must selectively transcribe parts of the DNA that makes up its genome into RNAs that specify the structure of proteins. The set of proteins synthesized by a cell in turn ...
... coiled--occur at precise locations along genes that are actively undergoing transcription. They also showed that RNA polymerase--the enzyme that reads genes as the first step in making proteins--is ...
RNA polymerase moves along the DNA molecule, copying its sequence of letters into ribonucleic acid. A protein called Rho binds to the newly-synthesised RNA a blocks the polymerase, ...
