$\huge\mathcal{\red{\underline{\purple{\pink{EXPLANATION}}}}}$

DNA is composed of nucleotides strung together to make a long chain called a polynucleotide.

DNA molecules have two polynucleotide chains, held together in a ladderlike structure. The sugar phosphate backbones of the two chains run parallel to each other in opposite directions.
