Figure 6.12.The genetic code gives rise to either overlapping or nonoverlapping reading sequences.
A codon consists of three consecutive nucleotides that code for an amino acid. The nucleotides in a
codon may give rise to multiple amino acids depending on the reading frame.
Figure 6.11.Polypeptide structure. The building block of a polypeptide is the peptide bond formed
between amino acids. Peptide bonds connect amino acids to create a polypeptide chain. Proteins are
formed through the association of individual polypeptide chains that may be identical to each other or
unique in sequence.
