Species specific protein--DNA interactions may determine the chromatin units of genes in S.cerevisiae and in S.pombe.

Abstract

Yeast genes, such as URA3, are chromatin units characterized by positioned nucleosomes and flanking nuclease sensitive regions (NSRs). To investigate the structural determinants at the chromatin level in vivo, the URA3 gene was dissected into three parts (U5', Umid and U3'), and the chromatin structures of the individual parts were analysed after insertion… (More)
