There was an error during DNA replication and this led to a mutation near or on the template sequence for the histidine responsible for the stability of the heme-myoglobin interaction What would happen if the codon for the histidine were changed from CAU to CAC? O a The protein would become unstable and the function may change, Ob. There would be no change to the RNA Oc. There would be no change to the protein structure or function od CAU is not a codon for histidine
