| Abstract |
Single positioned nucleosomes have been extensively employed as simple model experimental systems for analysis of various intranuclear processes. Here we describe an experimental system containing positioned mononucleosomes allowing transcription by various RNA polymerases. Each DNA template contains a pair of fluorescent labels (Cy3 and Cy5) allowing measuring relative distances between the neighboring coils of nucleosomal DNA using Forster resonance energy transfer (FRET). The single-particle FRET (spFRET) approach for analysis of DNA uncoiling from the histone octamer during transcription through chromatin is described in detail. |
