What is the DNA sequence that the mRNA sequence 5′-AUG CCU AGC-3′ was translated from?
A) 3′-AUG CCU AGC-5′
B) 3′-CGA UCC GUA-5′
C) 3′-UAC GGA UCG-5′
D) 3′-TAC GGA TCG-5′
E) 3′-ATG CCT TCG-5′

Question

Quizplus · Accepted Answer

The mRNA sequence 5′-AUG CCU AGC-3′ corresponds to the DNA template strand 3′-TAC GGA TCG-5′, considering that in DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G), and vice versa. The mRNA is read in the 5′ to 3′ direction, and its bases are complementary to the DNA template strand.
