Understand the structure of a nucleotide: A nucleotide is the basic building block of nucleic acids (DNA and RNA). It consists of three components: a phosphate group, a sugar (deoxyribose in DNA or ribose in RNA), and a nitrogenous base.
Examine the image provided in the problem. Identify the components of the nucleotide by looking for the phosphate group, the sugar, and the nitrogenous base.
Determine which part of the image corresponds to the nucleotide as a whole. The nucleotide will include all three components (phosphate, sugar, and base) connected together.
Match the labeled parts of the image (A, B, C, D) to the nucleotide structure. Look for the label that encompasses all three components of the nucleotide.
Select the correct letter (A, B, C, or D) that corresponds to the nucleotide in the image based on your analysis of the structure.
