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. With the exception of identical twins, all humans show significant variation in genomic DNA sequences. The human reference genome (HRG) is used as a standard sequence reference. There are several important points concerning the human reference genome: • The HRG is a haploid sequence. Each chromosome is represented once.
