3. If the sequence of one strand of DNA is written as follows:
5'-ATGCATGCATGCATGCATGCATGCATGC-3'
Write down the sequence of complementary strand in direction.
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'
