Molecular mechanisms of chromatin transcription by RNA polymerase III. Part 1

Chromatin provides for the dense packing of DNA in eukaryotic cell nuclei and its proper functioning. The present review describes mechanisms of chromatin transcription by RNA polymerase III (RNAP III).

Description
Summary:Chromatin provides for the dense packing of DNA in eukaryotic cell nuclei and its proper functioning. The present review describes mechanisms of chromatin transcription by RNA polymerase III (RNAP III). This mechanism is characteristic of eukaryotic RNAP III, some bacteriophage RNAPs, and many ATP-dependent chromatin remodeling complexes. During the remodeling of chromatin according to this mechanism, nucleosomes move along the DNA molecule without octamer release into the liquid phase.
