    What are the protein sequences encoded by repeating units of:

    a) GGG
    b) GGA
    c) GGC
    d) GGU

    If the sequences are read in different reading frames, how does this affect the resulting protein sequence?

    Solution Summary

    This solution provides the protein sequence encoded by a repeating unit of the GGx trinucleotide, where x is any of the four nucleotides. It also shows how reading the RNA sequence in different reading frames affects the resulting protein sequence.
