How does RNA differ from DNA?
A.RNA uses ribose and uracil instead of deoxyribose and thymine
B.RNA contains thymine and DNA contains uracil
C.RNA is always double-stranded
D.RNA lacks phosphate groups
Explanation
Core Concept
RNA's 2′-OH on ribose makes it less stable than DNA, and uracil replaces thymine. RNA is also usually single-stranded.
Correct Answer
ARNA uses ribose and uracil instead of deoxyribose and thymine
