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?

The genetic code is essentially the same for all organisms. based on this information, one can logically assume which of the following statements to be correct? a. dna was the first genetic material. b. the same codons in different organisms translate into the different amino acids. c. different organisms have different numbers of different types of amino acids. d. a gene from an organism can theoretically be expressed by any other organism. e. all organisms have experienced convergent evolution.
