The nitrogenous bases of the opposite strands wind around each other to form a twisted ladder-like structure. These two strands run in opposite directions. This structure is known as the double helical structure of eukaryotic DNA. Whereas, eukaryotic DNA occurs as a linear form of DNA with two ends.
