What would the complementary strand of DNA if one side has the nucleotide order of TTG CAC TAC

TTG CAC TAC
AAG GAG ATG
AAC GTG ATG
CAT TAC CAT
All of the above are correct

All of the above sequences could potentially be the complementary strand of DNA for the given strand (TTG CAC TAC). The complementary strand will have the same nucleotides but with their complement bases (A with T, T with A, G with C, and C with G).

Therefore, the complementary strands for the given strand (TTG CAC TAC) would be:
- AAG GAG ATG
- AAC GTG ATG
- CAT TAC CAT

All of these options are correct as they satisfy the criteria for the complementary strand.
