Instructions
Student Worksheet - pg 1 of 2 (open Box #2 to enter numbers into Table 1) We
will share data collection. Each student will be given one of the pairs of
organisms to count. Data will then be shared.

Question 1
1.
Last Name First Name
enter your name
Question 2
2.
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.

Question 12
12.
this is a node, enter the number of differences from your Table 1 between these organisms (#10 and #11)
Question 13
13.
this is a node, enter the number of differences from your Table 1 between these organisms
Question 14
14.
this is a node, enter the number of differences from your Table 1 between these organisms (#7 )
Question 15
15.
this is a node, enter the number of differences from your Table 1 between these organisms (#8 & #9)
Question 16
16.
this is a node, enter the number of differences from your Table 1 between these organisms (#6 & #7)
Question 17
17.
this is a node, enter the number of differences from your Table 1 between these organisms (#5 & #6)
Question 18
18.
this is a node, enter the number of differences from your Table 1 between these organisms (#3 & #5 or #4 & #5); there is more than one correct answer, however, enter only one of the numbers
Question 19
19.
Look at the set of amino acid sequences you used to collect data
Question 20
20.
enter the animal's name that goes on this branch; use lower case letters
Question 21
21.
enter the name of the animal that goes on this branch; use only lower case letters
Question 22
22.
enter the name of the organism that belongs on this branch; use only lower case letters
Question 23
23.
enter a number
Question 24
24.
enter a number
Question 25
25.
Question 26
26.
The fewer the differences in cytochrome C amino acids indicates the organisms
are more closely related.
Question 27
27.
This lab is an indirect DNA analysis.
Question 28
28.
Question 29
29.
Wheat is the plant and yeast is the fungi in this study. All of the other
organisms in this study are animals (including the moth). The differences of
sequences is in the 40's for both yeast and wheat compared to all of the other
organisms.
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."
True
False
The branch should be added
A as a separate branch starting at the same node as the moth; on side closest to the snake line
B off the same branch line as the moth, but not at the node; on side closest to the snake
C off the same branch line as the moth, but not at the node; on side closest to the wheat
D as a separate branch starting at the same node as the wheat and yeast.
List 3 things you used to determine how organisms are related to each other.
A the study of trace, mold and cast fossils
B the study of anatomy (body structure), embryology (development before birth),
and behavior
C direct or indirect comparison of DNA base sequences, including other molecular
evidence
D A, B, and C are all correct
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.
True
False
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.
