Organize these options into the right categories

Groups:

(a) Purines

,

(b) Pyrimidines

• Adenine

• 1 ring

• Cytosine

• Guanine

• Thymine

• 2 rings

Why does the A always pair with T, and C always pair with G?

• C and G are both rounded letters

• A and T both have 2 rings

• C and G both have 3 bonds to make

Which parts of a DNA strand are different from person to person?

• the hydrogen bonds

• the deoxyribose sugars

• the sequence of nitrogenous bases

• the type of nitrogenous bases

• the phosphate arrangement
