Question

In nucleic acids, nucleotides are linked by:

NISHANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [Option D]
## CONCEPT FRAMEWORK
	**Primary Concept**: Nucleic acid structure
	**Related Topics**: Nucleotide composition, DNA/RNA structure
	**Prerequisites**: Understanding of molecular biology basics
## SOLUTION PATHWAY
**Given Information**:
		- Nucleotides are the monomers of nucleic acids (DNA and RNA).
		- The chemical bonds that connect them determine the structure of the nucleic acid.
**Method & Steps**:
	1. Identify the types of bonds in biological molecules.
		Reasoning: Nucleotides consist of a phosphate group, a sugar, and a nitrogenous base.
		Formula/Rule: The linkage involves the phosphate group of one nucleotide and the sugar of another.
	2. Determine the specific bond type connecting nucleotides.
		Working: Nucleotides are joined via a phosphate group that forms a bond with the hydroxyl group of the sugar in the next nucleotide.
		Key Point: This forms a sugar-phosphate backbone.
	3. Conclude on the type of bond formed.
		Result: Nucleotides are linked by phosphodiester bonds.
		Verification: Phosphodiester bonds are a well-documented feature of nucleic acids, forming the structural framework.
## OPTION ANALYSIS
[A] :x: Glycosidic linkages are found in carbohydrates, not nucleic acids.
[B] :x: Peptide bonds link amino acids in proteins, not nucleotides.
[C] :x: Hydrogen bonds are crucial for base pairing in nucleic acids but do not link nucleotides.
[D] ✓: Phosphodiester bonds are the correct type of linkage between nucleotides in nucleic acids.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing glycosidic bonds with phosphodiester bonds: Remember that glycosidic bonds connect sugars to nitrogenous bases in nucleotides, while phosphodiester bonds connect the sugar and phosphate of adjacent nucleotides.
		2. Misunderstanding the role of hydrogen bonds: These are important for stabilizing the double helix structure of DNA but do not link nucleotides themselves.
	**Quick Tips**:
		1. Remember "P" for phosphodiester to connect phosphate and sugar in the backbone.
		2. Visualize the structure of DNA/RNA to reinforce how nucleotides are arranged and linked.
