WebWhen coupled to RNA polymerase (RNAP), the translating ribosome ensures transcriptional processivity by preventing RNAP backtracking. Recent advances in the field have characterized important linker proteins that bridge the gap between transcription and translation: In particular, the NusE (S10):NusG complex and the NusG homolog, RfaH. WebDNA in eukaryotic cells is wrapped around nucleosomes that can act as a barrier to the binding of RNA polymerase and other proteins necessary for transcription. Eukaryotic cells overcome this barrier by employing three different classes of enzymes: nucleosome-remodeling complexes, histone chaperones, and enzuems that add and remove histone …

WebRNA is transcribed from the DNA to make these proteins (the central dogma, Figure 1). RNA is transcribed and processed within the nucleus, it then moves through the nuclear pores for protein translation in the cytoplasm. In this sense, DNA and RNA are the perfect partners in crime.
