What is the complementary sequence to 3’ ATG CGA ATA 5’?
*
1/1
3’ TAT TCG CAT 5’
3’ TAC GCT TAT 5’
3’ GAT AGC ATA 5’
5’ ATA AGC GTA 3’
Feedback
The correct answer is 3' TAT TCG CAT 5'. Remember complementary means “Matching or Pairing”
You have to remember to pay attention to your numbers as well as your letters (A-T, G-C, 5'-3'). The
correct answer is
3’ ATG CGA ATA 5’ (original sequence)
5’ TAC GCT TAT 3’ (complementary sequence)
But we asked for it in the 3’ direction, so mirror answer to give correct answer:
3’ TAT TCG CAT 5’
