What is the difference between a ribonucleic acid and a deoxyribonucleic acid?
A) Deoxyribonucleic acids have a 2'H instead of the 2'OH found in ribonucleic acids.
B) Deoxyribonucleic acids are used to build nucleic acid strands, while ribonucleic acids are used exclusively in enzymatic reactions.
C) Ribonucleic acids have a 3'OH, while deoxyribonucleic acids have a 3'H.
D) Deoxyribonucleic acids have fewer oxygen groups and so are found only in monophosphate form in the cell, while ribonucleic acids have more oxygen groups and are found only in triphosphate forms.
E) Ribonucleic acid include A, T, G, and C, while deoxyribonucleic acids include A, U, G, and C.

Question

Quizplus · Accepted Answer

The key structural difference between RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) is that RNA contains a hydroxyl group (OH) at the 2' position of its sugar (ribose), whereas DNA contains a hydrogen atom (H) at the 2' position of its sugar (deoxyribose), making it "deoxy." This difference is crucial for their respective functions and stability.
