Solution

The correct option is D 5' TAAGCGATA 3'
Complementary is one of the unique character of DNA that makes it less reactive and suitable genetic material.
The sequence of nucleotides in one strand is 3' ATTCGCTAT 5'
The sequence of nucleotides in one strand is 5' TAAGCGATA 3'
So the correct option is '5' TAAGCGATA 3'.
