Activity 4: Molecular Evidence Assignment

The Molecular Connection
1. Find the human, rhesus monkey, kangaroo, snapping turtle, bullfrog, and tuna on the "Amino Acid Sequences in Cytochrome-C Proteins from 20 Different Species" chart and underline their names.
2. Compare the human amino acid sequence with each of these five animals by counting the number of times an amino acid in that animal’s cytochrome c is different from the amino acid in that same position of the human sequence. For example, the number of differences between human and dog =10.
