A DNA template having the base sequence 3' A-G-A-T-G-A 5' would produce a mRNA with a base sequence of
A)5' A-G-A-T-G-A 3'.
B)5' U-C-U-A-C-U 3'.
C)5' T-C-T-U-C-T 3'.
D)5' T-C-T-A-C-A 3'.
E)5' A-C-A-U-C-A 3'.

Question

Quizplus · Accepted Answer

DNA to mRNA transcription follows the base pairing rule where A pairs with U, T pairs with A, C pairs with G and G pairs with C. 
So, the complementary base sequence of the given DNA template would be: 
5' T-C-A-T-C-T 3'. 
Thus, the mRNA sequence would be: 
5' U-C-A-U-C-U 3'. 
Therefore, the correct answer is B.

A DNA Template Having the Base Sequence 3' A-G-A-T-G-A 5
