Question

If the sequence of one strand of DNA is written as 5'-ATGCATGCATGCATGCAATGC-3' Then how you will write the sequence of complementary strand in 5'→3' direction.

Answer 1

TACGTACGTACGTACGTTACG

Answer 2

Answer:

With regards to base sequence, DNA strands are complementary to each other. Therefore, if the sequence of one strand of DNA is written as:

5′ -ATGCATGCATGCATGCATGCATGCATGC-3′

The sequence of the complementary strand in 3′ -> 5′ is as follows:

3′ – TACGTACGTACGTACGTACGTACGTACG – 5′

Subsequently, sequence of complementary strand in 5’→3′ direction is written as:

5′ – GCATGCATGCATGCATGCATGCATGCAT – 3′
