Question

What would be the complementary sequence of DNA to this molecule? ATT CGT AGG ACT


UAA GCA UCC UGA


TAA GCA TCC TGA

Answer 1

Base‑pairing rules: A pairs with T, and C pairs with G (in RNA, U replaces T).

If the given strand is written 5'→3':
5'-ATT CGT AGG ACT-3'

the complementary (antiparallel) strand is:
3'-TAA GCA TCC TGA-5'

If you prefer the complementary strand written 5'→3', reverse that:
5'-AGT CCT ACG AAT-3'

Also, the RNA complement (T → U) would be:
5'-UAA GCA UCC UGA-3' (or 3'-UAA GCA UCC UGA-5' depending on orientation).
