Ans.
DNA replication involves formation of two identical copies from DNA from a single parent DNA molecule. The parent DNA strands act as template, and new DNA strands are made by DNA polymerase enzyme, complementary to parent strands.
According to base-pair rule, adenine (A) pairs with thymine (T) and Guanine (G) pairs with cytosine (C). Thus, the sequence TGCATA will bind to the sequence ACGTAT.
Thus, the correct answer is 'option C). TGCATA.'
