Statement A : In DNA double helix structure, the two strands of polynucleotides are parallel i.e., run in the same direction. Statement B : In DNA double helix structure, the backbone is formed by the sugarphosphate- sugar chain.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
DNA exists as a double helix. The two strands of polynucleotides are antiparallel i.e., run in the op-posite direction.
