Which statement contrasts DNA and RNA correctly?
A.DNA has deoxyribose and thymine; RNA has ribose and uracil
B.DNA is single-stranded; RNA is double-stranded
C.Both use thymine
D.RNA contains deoxyribose
Explanation
Core Concept
DNA's sugar lacks the 2′ hydroxyl and its bases include thymine; RNA uses ribose and uracil. DNA is double-stranded and stable; RNA is typically single-stranded.
Correct Answer
ADNA has deoxyribose and thymine; RNA has ribose and uracil
