WebAnswer: 1.Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. 28. WebExplain how purines and pyrimidines are located in a DNA molecule. In a DNA molecule, there is just enough room between the two sugar-phosphate backbones for one purine and one pyrimidine molecule, so a purine in one strand must always be opposite a pyrimidine in the other. pairing of bases.
