3' GCTTAGTCCG 5' Which of the following nucleotide base sequences complements the section of DNA modeled above? A. 3' TAGGCTGAAT 5' B. 3' CGAATCAGGC 5' C. 3' CGTTAACGAG 5' D. 3' GCTTAAGTCA 5'.
the complementary strand would be - 5' CGAATCAGGC 3'
3' GCTTAGTCCG 5'; - strand 5' CGAATCAGGC 3' - complimentary strand So there is no correct answer i guess. But if we change the polarity(change 3' to 5' and 5' to 3') of option B, then B would be the correct answer.
