- ‘Replicative DNA polymerases are very accurate enzymes with error rates usually in the range of 10-5 per replicated nucleotide.’
- ‘The presence of the histones and CpG methylation most affect accessibility of the chromatin to RNA polymerases and transcription factors.’
- ‘These complexes regulate the interaction of RNA polymerases and DNA elements within promoters.’
