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

To find the complementary strand, we need to use base pairing rules. A pairs with T, and C pairs with G. So the complementary strand of 5'-ATCGCAACTGTCACTA-3' would be 3'-TAGTGACAGTTGCGAT-5'.
