1. Lets make a “T” diagram and list the differences between the two.
RNA vs. DNA
Lets make a “T” diagram and list the differences between the two.
Written and produced by the great one himself: Mr. West

2. DNA RNA DNA vs. RNA deoxyribose sugar nitrogen bases double stranded
G, C, A, T
T = thymine
T : A
C : G
double stranded
RNA
ribose sugar
nitrogen bases
G, C, A, U
U = uracil
U : A
C : G
single stranded

3. Is Uracil a purine or pyrmidine?
Who says Purine?
Who says Pyrmidine?

4. The answer is:
PYRIMIDINE
Why?
Because the “T” in DNA was replaced with “U” in RNA. Since “T” in DNA is a Pyrimidine, “U” has to be a Pyrimidine.
