Question

Question 3: 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

Class 12 - Biology - Molecular Basis of Inheritance Page 125

Answer 1

Hii friend,

According to palindrome sequence, the order can be written as,

5'-ATGCATGCATGCATGCATGCATGCATGC-3'

3'-CGTACGTACGTACGTACGTACGTACGTA-5'

IT IS IN THE BASIs OF cytosine, guanine, adenine and thymine.

Hope this helps you a little!!!

Answer 2

The DNA strands are complementary to each other with respect to base sequence. Hence, if the sequence of one strand of DNA is

5'- ATGCATGCATGCATGCATGCATGCATGC − 3’

Then, the sequence of complementary strand in direction will be

3'- TACGTACGTACGTACGTACGTACGTACG − 5’

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

5'- GCATGCATGCATGCATGCATGCATGCAT− 3’
