RNA vs DNA Structure Comparison - Nucleic Acid Differences Explained #239361 (License: Personal Use)

This diagram contrasts the molecular architecture of RNA and DNA, emphasizing that RNA contains uracil (U) and a hydroxyl group on the 2′ carbon of its ribose sugar, while DNA uses thymine (T) and lacks that hydroxyl group, making it more chemically stable. Both feature antiparallel strands held by complementary base pairing (A-U/T, C-G), but RNA is typically single-stranded and more prone to degradation. The surrounding labeled nucleobase structures reinforce recognition of purines (A, G) and pyrimidines (C, U, T).
