Biochemistry C 785 Readiness Check II 2020
What is the complementary sequence to 3’ ATG CGA ATA 5’? (0/1 Points) 3’ TAT TCG CAT 5’ 3’ TAC GCT TAT 5’ 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’ If you chose 3' TAC GCT TAT 5', this is incorrect. Although the nucleotides are in the correct order, the 5' and 3' are in the wrong place. DNA strands that are complementary run-in opposite directions. This means that if one strand starts with a 3', the complementary strand must start with a 5'. If none of the answer choices give the correct answer in 5' --- 3', then you need to write its mirror, which will run from 3' --- 5'. 3’ GAT AGC ATA 5’ 5’ ATA AGC GTA 3’
