In Hybrid RNA-DNA, DNA is 5CTTAAG3. The sequence of RNA will be: (A) 5CTTAAG3, (B) 5CUUAAG3, (C) 5GAATTC3, (D) 5GAAUUC3
Answer is B. The RNA transcript with a 5' to 3' polarity is complementary to the template strand with its 3' to 5' polarity.
So, the complementary RNA of template DNA (5'CTTAAG3') will be 3'GAAUUC5' (i.e. 5'CUUAAG3').
