Deoxyribonucleic Acid Content of Haploid and Diploid Aspergillus Conidia


In 1948, Boivin, Vendrely and Vendrely1 suggested that the somatic nuclei of a vertebrate species may contain a fixed amount of deoxyribonucleic acid that is double the amount present in the germ cells. Since then, a considerable volume of evidence has been obtained to support this view2 3. Some apparent exceptions, such as rat liver, have been found, but these can be explained by the presence of nuclei with different degrees of ‘ploidy’. The evidence is consistent with the view that in resting nuclei a specific amount of deoxyribonucleic acid is associated with each set of chromosomes4.
