    I was wondering,

    if you had
    T C T (codon 47)

    C G G (...48)

    T G G (...49)

    G T C (...50)

    C C A(...51)

    and codon 49 was replaced by a START codon, what would happen? Would it be only 48 amino acid chain long? or no protein created...?

    Thank you!

    ATG (the start codon) encodes an amino acid, methionine, that can be found at any position in a protein. So a 'start' codon at 49 would just encode methionine in place of whatever amiuno acid should be there, with no effect on the rest of the protein
