the mRNA squence below is shown along with the polypeptide which would be produced when it is translated .what polypeptide would be produced if the fifth base in the mRNA sequence shown had been changed to A as result of a mutation in the DNA from which the mRNA wa transcribed ?

Question

the mRNA squence below is shown along with the polypeptide which would be produced when it is translated .what polypeptide would be produced if the fifth base in the mRNA  sequence  shown had been changed to A as result of a mutation in the DNA  from which the mRNA wa transcribed ?
AUG  UGU  AAU  GGG
Met   Cys Asn  Gly
