Question
**1. Fill in the blanks** - This molecule is a purine - This molecule is part of the sugar-phosphate backbone - This bond is broken during replication - This molecule is a sugar The image includes a diagram of the DNA double helix structure. The diagram highlights the following features: - **A**: Points to one of the nitrogenous bases in the helix, which could represent either adenine (A) or guanine (G), both of which are purines. - **B, C, D, E**: Indicate different parts of the DNA structure. Typically, labels in DNA diagrams could refer to: - Part of a nucleotide (such as a sugar or phosphate group). - Specific hydrogen bonds between complementary bases, which are disrupted during DNA replication. The diagram illustrates the base pairing rules and the double helix's sugar-phosphate backbone.
