Here's , Your Answer :-
=) The two strands in DNA molecule are held together through hydrogen bonds between purine base of one strand and pyrimidine base of another and vice-versa because of different sizes and geometries of all the base that only paring in DNA are G (guanine) and C (cytosine) through three H-bonds and between A (Adenine) and T (Thymine) through two H-bonds . Due to this base pairing principle the sequence of bases in the other strand . Thus , the two strands are not identical but are complimentary .

A In the DNA structure which is helical in shape have the total of two strands together that are bonded with the help of a hydrogen bond as per the base pairs.
The cytosine will form up with the guanine compound with the hydrogen bond. Whereas adenine will form thymine with the hydrogen bond.
Hence the two will be complimentary to each other.
