WebDNA has a double-helix structure, with sugar and phosphate on the outside of the helix, forming the sugar-phosphate backbone of the DNA. The nitrogenous bases are stacked in the interior in pairs, like the steps of a staircase; the pairs are bound to each other by hydrogen bonds. The two strands of the helix run in opposite directions, so that ... WebThe antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way. What is meant by antiparallel in DNA? Antiparallel: A term applied to two molecules that are side by side but run in opposite directions. The two strands of DNA are antiparallel.
