Question description

Suppose that the following sequence is a complete prokaryotic mRNA. 5'-AUGGAGUAAGGAGGUCGACAUGCUAGGAUUUUGUUAGCCAUAA-3'

Give a mutated form of this sequence that is of the same length, differs in sequence by only one base, but results in a shorter polypeptide. This was the answer given:

5'-UAAGAGGAGGUCGACAUGCUAUGAUUUUGUUAGCCAUAA-3' The changed base is underlined.

Does the polypeptide in the mutated sequence start at the second AUG? Also, why has the beginning of the sequence been altered-UAAGGAGGU to UAAGAGGAGGU
