What does T pair with in RNA?
Understand the Problem
The question is asking about the base pairing rules in RNA, specifically what base pairs with adenine (represented by 'A') in RNA. In RNA, adenine pairs with uracil (U) rather than thymine (T), which is found in DNA.
Answer
In RNA, T is replaced with U, so A pairs with U.
In RNA, the base thymine (T) from DNA is replaced with uracil (U). Therefore, adenine (A) pairs with uracil (U) in RNA.
Answer for screen readers
In RNA, the base thymine (T) from DNA is replaced with uracil (U). Therefore, adenine (A) pairs with uracil (U) in RNA.
More Information
In RNA, uracil is used instead of thymine because it is structurally similar but more suitable for RNA's single-stranded configuration.
Tips
A common mistake is assuming thymine is present in RNA, whereas uracil is actually the complementary base to adenine in RNA.
