A strand of DNA with the sequence 5'-ATTCCG-3'would have a complementary strand with the sequence
A) 5'-TAAGGC-3'.
B) 5'-ATTCCG-3'.
C) 5'-ACCTTA-3'.
D) 5'-CGGAAT-3'.
E) 5'-GCCTTA-3'.

Question

Quizplus · Accepted Answer

The complementary DNA strand is formed by pairing adenine (A) with thymine (T) and cytosine (C) with guanine (G). Therefore, the complementary sequence to 5'-ATTCCG-3' is 3'-TAAGGC-5', which is written as 5'-CGGAAT-3' in the 5' to 3' direction.
