### Step-by-Step Solution: 1. **Understanding DNA Structure**: - DNA (Deoxyribonucleic Acid) has a double helix structure, where two strands run in opposite directions. The backbone of each strand is made up of alternating sugar and phosphate groups. 2. **Identifying the Bases**: - The four nitrogenous bases in DNA are Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). These bases are attached to the sugar molecules in the backbone. ...
