Question of the day

Which statement accurately describes DNA and RNA with respect to structure and persistence?

Explanation:
DNA tends to be double-stranded and chemically more stable, which lets it serve as a durable, heritable store of genetic information across many generations. The double-stranded form, with base pairing, protects the sequence and makes accurate replication possible, while the absence of the 2'-hydroxyl in DNA’s sugar (deoxyribose) makes it less prone to hydrolysis, contributing to its persistence. RNA, in contrast, is usually single-stranded and contains ribose with a 2'-OH group, which makes it more chemically reactive and prone to degradation. This inherent instability aligns with RNA’s roles as a short-lived messenger, catalyst, or regulator that is synthesized as needed and rapidly turned over. So, describing DNA as double-stranded and longer-lived best matches how these nucleic acids are structured and maintained in cells.
