Note for numbers 1 and 2: Use the three-letter abbreviation of amino acid; separate amino acids with a hyphen: do
not include the stop codon.
Example: ala-cys-glu
1. Using the table of the genetic code, determine the sequence of amino acids. ala-ser-leu-asn
2. If mutation occurs by substitution of the 6th nucleotide with adenosine-5'- monophosphate, what is the resulting
amino acid sequence?
3. What type of mutation occurred? Choose from same sense, missense and non-sense.
For each of the following items, fill in either the DNA strand, the MRNA codons, the tRNA anticodons, or the
amino acid sequence that have been left blank. If several sequences might work, choose only one.
Furthermore, circle the start and the stop codons of each mRNA sequence.
