    Genome size and the proportion of repeated nucleotide sequence DNA in plants (1974)
    Springer
    Biochemical genetics 12 (1974), S. 257-269 
    Details
    ISSN: 1573-4927
    Keywords: DNA ; repeated sequences ; plant DNA
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The reannealing kinetics of denatured DNA fragments from 23 species of higher plants have been studied, using hydroxylapatite chromatography to distinguish reannealed from single-stranded DNA. The 2C nuclear DNA contents of the species varied between 1.7 and 98 pg. The proportions of DNA in species with a nuclear DNA mass above 5 pg that reannealed with the kinetics of sequences present in more than 100 copies were high (69–92% with a mean of 80±2.0%). For species with less than 4 pg of DNA, the mean proportion of repeated-sequence DNA was 62±2.9%. It is concluded that most of the variation in nuclear DNA mass in higher plant chromosomes can be accounted for by variation in repeated-sequence DNA. The consequences of altering the adapted DNA content of a species by the addition of families of repeated sequences are discussed in relation to the proportion of repeated-sequence DNA.

    Kinetics of reassociation of DNA from the thymus and ascites hepatoma of rats (1974)
    Springer
    Bulletin of experimental biology and medicine 78 (1974), S. 1311-1312 
    Details
    ISSN: 1573-8221
    Keywords: normal cells ; tumor cells ; DNA ; molecular hybrids
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract The kinetics of renaturation of DNA from the rat thymus and ascites hepatoma was studied. Three zones were distinguished on the curve, corresponding to fast, intermediate, and slow rates of DNA reassociation. The course of the reassociation curves of DNA from tumor and normal tissues did not diverge in any of these zones. Consequently, no difference could be detected between the DNA's of normal and neoplastic cells on the basis of their reassociation kinetics.
