Which of the following 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'-ATCACTGTCAACGCTA-3'
D)5'-TAGTGACAGTTGCGAT-3'

Question

Quizplus · Accepted Answer

The complementary strand for any DNA sequence is created by pairing A with T and C with G. Therefore, the complementary strand to 5'-ATCGCAACTGTCACTA-3' would be 5'-TAGTGACAGTTGCGAT-3'. Option A has the correct beginning and end, but the middle of the sequence is incorrect. Option B is incorrect because RNA uses uracil (U) instead of thymine (T), and RNA is not being requested here. Option C is incorrect because the sequence is not complementary in its nucleotide pairing.
