If I am understanding correctly, the first thing they are asking you to do is match nitrogen bases.
Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).
Then, whichever are the double strands, cut them out and put them into you notebook. (I am not sure where the notebook is, but I am assuming you know)
Then in the speech bubble next to the picture of Chargaff- <u>talk about his rule. </u>
What does the rule mean?
What does the rule explain?
How is the rule demonstrated?
Lastly, finding percents. <em>What percent of the pairs has Adenine in them? </em>
For example:
If I look at this pairing below
A →T
T→ A
G →C
C→ G
50% of the pairs include Adenine.
