Human genetic material (DNA) is made up of sequences of the molecules adenosine (A), guanine (G), cytosine (C), and thymine (T), which are called bases. A codon is a sequence of three bases. Replicates are allowed, so AAA, CGC, and so forth are codons. Codons are important because each codon causes a different amino acid to be included in a protein. a. How many different codons are there? b. How many different codons are there in which all three bases are different? c. The bases A and G are called purines, while C and T are called pyrimidines. How many different codons are there in which the third base is a purine and the others are pyrimidines?
