What is the complement of the following sequence of DNA: 5'-CCTATCGA-3'?
A) 5′-CCTATCGA-3′
B) 3′-CCTATCGA-5′
C) 3′-AGCTATCC-5′
D) 5′-GGATAGCT-3′
E) 5′-TCGATAGG-3′

Question

Quizplus · Accepted Answer

The complement of a DNA sequence is formed by pairing adenine (A) with thymine (T) and cytosine (C) with guanine (G). The given sequence is 5'-CCTATCGA-3', so the complement is 3'-GGATAGCT-5', which is written as 5'-TCGATAGG-3' when reversed.
