In wild type E. coli a 3'- G-T-A- 5' triplet of DNA nucleotides is transcribed into a codon that is translated into an amino acid in a functioning polypeptide. If there is a nucleotide pair substitution mutation that swaps the adenine in the DNA triplet for a cytosine, this would result in: O there being no change in the primary, secondary or tertiary structure of the mutant polypeptide. O there being a change in primary structure and possible changes in the secondary and tertiary structure of the mutant polypeptide. O a premature stop codon being generated so the mutant polypeptide would be shorter than the wild type. O a codon frameshift causing extensive missense that means all the amino acids in the polypeptide after the mutation would be different from the wild type. Figure 5.
