Therefore, while bacteria accomplish transcription of all genes using a single kind of RNA polymerase, the use of different sigma factor subunits provides an extra level of control. Eukaryotic ...

Transcription is the process by which an RNA polymerase synthesizes ribonucleic acid (RNA) using deoxyribonucleic acid (DNA) as a template. The RNA binding protein hnRNPL is recruited to chromatin ...
