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?

Respuesta :

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.
