Torsional state of DNA in a transcriptionally hyperactive Balbiani ring of polytene chromosomes.
Gruzdev AD, Lezzi M. Gruzdev AD, et al. Chromosome Res. 1998 Aug;6(5):367-78. doi: 10.1023/a:1009296404879. Chromosome Res. 1998. PMID: 9872666
Isolated nuclei of salivary glands were stained with the intercalating fluorescent dye ethidium bromide (EtBr) at various concentrations, and the temporal fluorescence intensity changes (deltaI/I per min) occurring in BR2 and in inactive bands were monitored under a confoc …
