Suppose the 5ʹ-to-3ʹ coding strand of DNA is GTCTATGCATTA. Which sequence represents the resulting transcribed RNA?
A) 5ʹ-GTCTATGCATTA-3ʹ
B) 5ʹ-GUCUAUGCAUUA-3ʹ
C) 5ʹ-CAGATACGTAAT-3ʹ
D) 5ʹ-CAGAUACGUAAU-3ʹ
E) 3ʹ-GUCUAUGCAUUA-5ʹ

The RNA is synthesized from the template strand of DNA in a 5ʹ-to-3ʹ direction, and it is complementary to the template strand. Since the given sequence is the coding strand, the RNA sequence will be identical to the coding strand except that thymine (T) is replaced by uracil (U) in RNA. Therefore, the correct sequence is 5ʹ-GUCUAUGCAUUA-3ʹ.
