Question

Quizplus · Accepted Answer

The primary structural difference between DNA and RNA is in the sugar component of their nucleotides. DNA nucleotides contain deoxyribose, while RNA nucleotides contain ribose. This difference in sugar structure results in subtle differences in the chemical properties of DNA and RNA. None of the other answer choices accurately describe the structural differences between DNA and RNA.
