The codon for the sixth amino acid is GAG. It mutates to GAA due to mutation 'A' and GUG due to mutation 'B'. Haemoglobin structure did not change as a result of mutation 'A' but mutation 'B' led to sickle cell-shaped RBCs. Explain giving reasons how could mutation 'B' change the haemoglobin structure and not mutation 'A'.
