What is the Nucleotide Sequence of the DNA Strand That

Question

What is the nucleotide sequence of the DNA strand that is complementary to 5'-ATCGCAACTGTCACTA-3'?
A) 5'-TAGCGTTGACAGTGAT-3'
B) 5'-UAGUGACAGUUGCGAU-3'
C) 5'-TAGCGTTGACAGTGAT-3'.
D) 5'-TAGTGACAGTTGCGAT-3'
E) 5'-ATCACTGTCAACGCTA-3'

Accepted Answer

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