title: Newly synthesised DNA of high molecular weight in the yeast Saccharomyces cerevisiae.
abstract: Two species of newly synthesised DNA larger than average replicons have been found in yeast. Their molecular weights are 60 million and 90 million daltons respectively. The exact nature of these molecules is not certain. They may represent entirely novel species of cellular DNA or they could be concatameric replication intermediates of some particular fraction of DNA, such as mitochondrial DNA or rDNA. Alternatively they could result from the fusion of adjacent completed replicons in a small cluster.
