The image depicts the molecular structure of a segment of DNA, focusing on the arrangement of nucleotide pairs and their hydrogen bonding. ### Diagram Explanation The diagram shows the complementary base pairing within DNA's double helix structure. There are two strands, each oriented in opposite directions, indicated by the 5’ to 3’ and 3’ to 5’ designations. Each nucleotide is comprised of a sugar-phosphate backbone connected to a nitrogenous base. #### Key Features: 1. **Nucleotide Bases**: The nitrogenous bases thymine (T), adenine (A), cytosine (C), and guanine (G) are highlighted. - **Adenine (A)** pairs with **thymine (T)**. - **Cytosine (C)** pairs with **guanine (G)**. - These pairings are held together by hydrogen bonds. 2. **Backbone Structure**: The phosphate-sugar backbone is illustrated as connected circles and lines running along each DNA strand. 3. **Complementary Pairing**: - Thymine and adenine are linked by two hydrogen bonds. - Cytosine and guanine are linked by three hydrogen bonds. - These bonds are indicated by dashed lines between base pairs. 4. **DNA Grooves**: - The "minor groove" and "major groove" of the DNA double helix are labeled at the bottom, indicating the spaces between the twisting strands where proteins often interact with the DNA. This depiction is informative for understanding DNA’s function in genetic coding and replication, as the sequence of these bases encodes genetic information.
