Abstract
The distribution of nuclear DNAs of nine species of the genus Brassica in CsCl density gradients was investigated. The amount of satellite DNA with buoyant density of 1.704 g - cm-minus3 varies widely between the species. The satellite component is completely absent in B. oleracea; in B. nigra its amount reaches 37%, and in the other species it occupies an intermediate position. The absence of satellite DNA in B. oleracea was demonstrated by equilibrium centrifugation using a Cs2SO4 density gradient, containing Hg2+.Entities:
