Abstract:
From a synchronized culture of Saccharomyces cerevisiae role=presentation style=font-size: 90%; display: inline-block; position: relative;> cells were harvested at different intervals during S-phase. The purified DNA of each sample was challenged with ribosomal RNA by specific DNA/rRNA hybridization. From the constant rDNA/DNA ratio observed it is concluded that in yeast, the replication of the rRNA cistrons is not restricted to a distinct interval but proceeds at a constant rate throughout the entire S-period.
