Snowman Mutations
advertisement
As snow days have become more and more common in our little town of Cass City, it is obvious that something fishy is going on with the weather. It is likely that due to all the tractors and all the toxins that have gone into the air, there are likely to be mutant snowflakes. Where there are mutant snowflakes, there are mutant snowmen. At the side of each DNA sequence, draw the snowman that results from the code. Use the codon chart to determine the amino acid sequence and then determine the directions for each code.

Phenylalanine = large circle Leucine = medium circle Isoleucine = small circle Methionine = place Valine = eyes Serine = carrot Proline = stick Threonine = hat Alanine = side Tyrosine = bottom Histidine = middle Glutamine = top Lysine = snake Cysteine = puppy Arginine = house Tryptophan = tire Glycine = spoon Glutamic acid = pumpkin Asparagine = on Teacher notes Normal Snowman ● ● ● ● ● ● ● 1.
