Which of the following correct ascending order of the number of the hydrogen bond in different DNA which are given below:
(a) 5'-AATAAAGC-3'; 3'-TTATTTCG-5'
(b) 5'-AATGCTGC-3'; 3'-TTACGACG-5'
(c) 5'-ATGCTGAT-3'; 3'-TACGACTA-5'
(d) 5'-GCATAGCC-3'; 3'-CGTATCGG-5'
(a) 5'-AATAAAGC-3'; 3'-TTATTTCG-5'
(b) 5'-AATGCTGC-3'; 3'-TTACGACG-5'
(c) 5'-ATGCTGAT-3'; 3'-TACGACTA-5'
(d) 5'-GCATAGCC-3'; 3'-CGTATCGG-5'
View answer and explanation
Correct option: A
a c b d
Option A (a < c < b < d) is correct because it represents the correct ascending order based on the number of hydrogen bonds in each DNA sequence.
