In DNA, specific bases pair together: Adenine with Thymine and Cytosine with Guanine. The complementary DNA sequence to GCTTATAT is TGAAUATA.
Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G) in DNA strands. To find the complementary DNA strand to GCTTATAT, we need to match bases accordingly. The correct sequence is TGAAUATA (opposite pairs: GC, TA, TA, TA, GC, TA, GC, TA).
