Question

Which statement correctly compares nucleic acids and carbohydrates?
They both contain carbon, but only nucleic acids contain hydrogen.
They both contain carbon, hydrogen, and oxygen in a 1:2:1 ratio.
They both contain carbon, but only carbohydrates contain oxygen.
They both contain carbon, but only nucleic acids contain phosphorous.

Answer 1

"They both contain carbon, but only nucleic acids contain phosphorous."

Reason: Carbohydrates are primarily C, H, and O (usually in a 1:2:1 ratio), while nucleic acids contain C, H, O, N, and P (the phosphate groups in the backbone).
