Your Name: _______________________________________________ Coyote DNA Analysis Find out what your animal looks like using only the DNA from your animal's chromosomes. Below is the key that is needed to determine what traits correspond to each amino acid sequence. 1. The DNA for your animal is coded on one side of the helix. Transcribe the DNA strand into mRNA. Don't forget the special base pair rules for RNA! Separate the triplets into codons by putting a mark after every 3 (three) bases. 2. Translate the mRNA into an amino acid chain. Use the amino acid chart to find the amino acid that corresponds to each codon. Remember, translation for each chain always starts with the amino acid methionine (Met) and ends with one of the stop codons (UGA, UAG, UAA). 3. Use the amino acid sequence to find which traits are produced. In this exercise, all traits will be seven amino acids long. Remember, in nature traits may be the result of several thousand amino acids. Traits can be found on the many different chromosomes found in the cells of each species. 4. Finally, create your animal by putting together all of the traits that you found. Draw the animal on a separate sheet of paper. Be creative!
