Lab Analysis - Please answer these in your notebook & tape this
packet into your notebook.
1. Refer to the Cytochrome C Amino Acid sequence list. How many
Cytochrome C amino acid differences exist between humans and
chimpanzees? What does this suggest about the similarity between these two
organisms?
2. Predict the number of Cytochrome C amino acid sequence differences you
would expect to see between a horse and a zebra.
3. What evidence did you use to make this prediction? (be specific!)
4. What causes the differences in amino acids between different organisms?
5. In this lab, we only analyzed the sequence of one specific protein
(Cytochrome C). If we analyzed more protein sequences organisms share,
would our conclusions of evolutionary relationships be stronger? Why or why
not?
6. Why will organisms that have evolved recently have fewer differences
between their amino acid sequences than organisms that evolved a long time
ago?
7. Based on what you have learned from this activity, summarize what
important information can be obtained from a cladogram.
