Question

Which of the following may be true for RNA?

• A. A = U, G = C
• B. A $\ne$ U, G $\ne$ C
• C. A = U = G = C
• D. Purines = Pyrimidines

Answer 1

The correct option is B A $\ne$ U, G $\ne$ C

• RNA is single-stranded, so there would be no reason to expect equal content of any bases.
• Because in RNA the pairing is not throughout as in DNA rather there are some folding(as in t-RNA).
• Hence, in RNA G is not equal to C and A is not equal to U.
• So, the correct answer is 'A ≠ U, G ≠ C'.
