Shown below are partial tRNA sequences with anticodons underlined. Which of these is tRNA #1, bringing the first amino acid to the ribosome during translation initiation? 5' - A U A U G A G U U C G - 3' 5' - A U A U A U G U U C G - 3' 5' - A U A U C A U U U C G - 3' none of the above Which of the following types of mutations has the HIGHEST probability of changing a SINGLE amino acid in the encoded protein, not changing any of the remaining amino acids?
