Vedclass · Answer

(B) $DNA$ $(Deoxyribonucleic 	ext{ acid})$ molecule consists of two polynucleotide chains that are coiled around a common axis to form a double helix structure.These two strands run in an anti-parallel direction, meaning one strand runs in the $5' 	o 3'$ direction and the other in the $3' 	o 5'$ direction.The nitrogenous bases of the two strands are linked together by hydrogen bonds, forming the rungs of the ladder-like structure.
