Question

If the sequence of one strand of DNA is written as follows: 5'-ATGCATGCATGCATGCATGCATGCATGC-3'

Write down the sequence of complementary strand in 5'→ 3' direction.

Answer 1

The correct sequence of complementary stand is as followed:

5′- GCATGCATGCATGCATGCATGCATGCAT- 3’

Step-by-step explanation:

In the given question the sequence of one DNA stand is

5′- ATGCATGCATGCATGCATGCATGCATGC – 3’

Since, the DNA strands are complementary to each other with respect to base sequence. Hence,

5′- ATGCATGCATGCATGCATGCATGCATGC – 3’ Then, the sequence of complementary strand in

3′- TACGTACGTACGTACGTACGTACGTACG – 5’ direction will be

Therefore, the sequence of nucleotides on DNA polypeptide in direction is

5′- GCATGCATGCATGCATGCATGCATGCAT- 3’
