Answer:
DNA double strands are run in opposite direction
Explanation:
The DNA is a macromolecule and is made of the polynucleotide. In a DNA, Polynucleotides are arranged in two strands or helices. The two strands are joined together by hydrogen bonds. Each stand has two ends. One end is called 5’ (5 prime) and the end is known as 3' (3 prime). The two stands in a DNA run in antiparallel or in an opposite direction. It means at one end, one strand is 3' and the other is 5' and at the other end one strand is 5' and another strand is 3'.
