Estudio comparativo de la cantidad de ADN en seis especies de Dinoflagelados
E. Costas, V. López-Rodas

A COMPARATIVESTUDY OF DNA CONTENT IN SIX DINOFLAGELLATE SPECIES. - The DNA content of six dinoflagellatespecies was precisely estimated using TEM stereological procedures. Closelyrelated species showed high differences for DNA content suggesting a speciationmechanism involving polyploidy. The DNA content was not related either to cellvolume or to growth-rate. All species showed the same DNA package ratio. Thenumber of chromosomes was related to total DNA content.
