Answers (1)

With regard to base pairs the DNA strand are complementary to each other. So, if the sequence of DNA is

 5'-ATGCATGCATGCATGCATGCATGCATGC-3'

The sequence of the complementary strand will be 

3`- TACGTACGTACGTACGTACGTACGTACG - 5`.

In 5' - 3' strand, it can be written as

5'- GCATGCATGCATGCATGCATGCATGCAT-3'
