Answer: TCGAACGAG.

Hope this helps ;) don't forget to rate this answer !

Step-by-step explanation:

TCGAACGAG correctly identifies the complementary DNA strand.

DNA is composed of nucleotide bases, which are held together by covalent bonds to form a double helix. The four bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). In DNA, the base pair A always pairs with T, and C always pairs with G. This means that if one strand of DNA has the base sequence ATCGGTACA, the other strand (the complementary strand) will have the base sequence TCGAACGAG.

So, in this case, the correct answer is TCGAACGAG.
