title: Sedimentation properties of yeast chromosomal DNA.
abstract: Sedimentation analysis of nuclear DNA released from spheroplasts of the yeast Saccharomyces cerevisiae indicates that it has a number average molecular weight of 6.2 x 10(8). The chromosomal DNA molecules range in size from as small as 5 x 10(7) daltons to as large as 1.4 x 10(9) daltons. Based on these values and estimates of the total DNA content of the yeast nucleus, it is proposed that each yeast chromosome contains a single DNA duplex.
