- The image displays a grid of nucleotide structures, each composed of a phosphate group, deoxyribose sugar, and a nitrogenous base.
- The key identifies the four DNA bases by their unique shapes: Adenine (flag), Cytosine (oval), Thymine (triangle), and Guanine (rectangle).
- The task is to identify the sequence of bases in the top row from left to right.
- Following the key, the first structure in the top row has a flag shape, corresponding to Adenine.
- The second structure has an oval shape, corresponding to Cytosine.
- The third structure has a rectangle shape, corresponding to Guanine.
- The fourth structure has a triangle shape, corresponding to Thymine.
- Therefore, the sequence of bases in the top row is Adenine, Cytosine, Guanine, Thymine.
