Web2 days ago · ASK AN EXPERT. Science Biology DNA is comprised of only 4 unique nitrogenous bases that code for all variation and all amino acids. If there were 6 unique nitrogenous bases instead of 4, how many would be the minimum number of bases required in each codon if there are only 20 amino acids? Explain how you reached that conclusion. WebEach nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T). Adenine and guanine are purines, meaning that their structures contain two fused carbon-nitrogen rings. Cytosine and thymine, in contrast, are pyrimidines and have a single carbon-nitrogen ring. buy marijuana seeds arizona
