Webb27 mars 2024 · Bonding Between Purines and Pyrimidines . While purines and pyrimidines include molecules that are active on their own (as in drugs and vitamins), they also form hydrogen bonds between each other to link the two strands of the DNA double helix and to form complementary molecules between DNA and RNA. In DNA, the purine adenine … Webb13 apr. 2024 · An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA. Attached to each sugar is one of four bases: adenine (A), uracil …
