Data from several papers by chargaff: for example,

e. chargaff et al., composition of the desoxypentose nucleic acids of four genera of sea-urchin, journal of biological chemistry 195: 155-160 (1952). does the distribution of bases in sea urchin dna and salmon dna follow chargaff's rules?

YES. The distribution of bases in sea urchin DNA and salmon DNA follow Chargaff's rules because the percentage of A bases is approximately equal to the percentage of T bases, and also the percentage of G bases is approximately equals to the percentage of C bases in both species. According to Chargaff's rule the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
