Figure 1.
Schematic representation of 35S RNA promoter in S. cerevisiae. Numbering is relative to the 35S transcriptional start (RIS). The ellipse indicates the first of five phased nucleosomes lying in the NTS. Positions of the most important DNA element are reported. The map position of the oligonucleotide (r3) used in this study for primer extensions is also reported (see text for details). ARS, autonomously replicating sequence.
