Answer: The complementary DNA strand is 3'TACGAACTGAC5'
Explanation: Watson and Crick base pair rule is that in DNA, adenine pairs with thymine and cytosine pairs with guanine. A DNA is a double stranded helix in which the two strands are complementary to each other. Being complementary means that they do not have the same base composition and sequence rather anywhere adenine is found in one strand, thymine is found the complementary strand and anywhere cytosine is found in one strand, guanine is found in the complementary strand.
