Cytochrome C Comparison Lab

Last Name First Name

Count the number of differences between each of the organisms cytochrome C amino acid sequence and place the number in the appropriate box in the table. See Instructions--> Method--> A--> numbers 1-4 for an example. We will count these as a class and put them on a shared google document. It will be easier for you to enter the data at one time after you have it on the class shared document.

I used personal knowledge. I have seen a picture of a live horse, donkey and zebra. All of them have similar body structures and look and act "horsey."

The branch should be added

List 3 things you used to determine how organisms are related to each other.

Select whether this a true or false statement to answer Question #6:

More closely related species have more recent common ancestors, therefore there has been less time for DNA mutations to occur and so their DNA is very similar and has less differences.

Select whether this is a true or false answer to Question #7:

This cytochrome C data indicates that plants and fungi originated off of the same node because they both have similar differences in sequences compared to all of the other animals. Animal life begins off of the next node (more recent) on the cladogram, so both plants and fungi are equal distance from the first node/branch of animals.
