Step 1: Understanding the Concept:
A nucleotide is the basic building block of DNA, consisting of a nitrogenous base, a pentose sugar, and a phosphate group. These components are connected by specific chemical bonds.
Step 2: Key Formula or Approach:
- N-glycosidic linkage: Connects the nitrogenous base to the C1' position of the pentose sugar.
- Phosphodiester linkage: Connects the phosphate group to the C5' of one sugar and the C3' of the next.
- Hydrogen bonds: Connect the two nitrogenous bases between complementary strands.
Step 3: Detailed Explanation:
The N-glycosidic bond specifically links the nitrogen atom of the nitrogenous base (purine or pyrimidine) to the carbon atom of the sugar molecule.
Step 4: Final Answer:
The N-glycosidic linkage is present between the nitrogenous base and the pentose sugar.
