the molecular mass the sequence of base pairs the distribution of electrical charges the folded three-dimensional shape
I gave my students this multiple choice question: What aspect of the DNA molecule encodes hereditary information concerning an organism's traits?

Only one answer is correct among these 4 choices:
- the molecular mass
- the sequence of base pairs
- the distribution of electrical charges
- the folded three-dimensional shape

Could you tell me which one is correct?

the sequence of base pairs
