Question:
In a DNA strand, the nucleotides are linked together by-----------.
In a DNA strand, the nucleotides are linked together by-----------.
Show Hint
The bond joins the phosphate of one nucleotide to the sugar of the next.
Updated On: Nov 12, 2026
- Glycosidic bond
- Phosphodiester bond
- Peptide bond
- Hydrogen bond
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
A DNA strand is a polynucleotide chain made of nucleotides joined one after another.
Step 2: Bond between nucleotides
The phosphate group links the 3' carbon of one sugar with the 5' carbon of the next sugar. This 3'-5' linkage is the phosphodiester bond and forms the sugar-phosphate backbone.
Step 3: Compare the options
An N-glycosidic bond joins a base to its sugar. Hydrogen bonds hold the two strands together. Peptide bonds occur in proteins.
Step 4: Conclusion
Nucleotides in one DNA strand are linked by phosphodiester bonds.
Final Answer:
Nucleotides in a DNA strand are joined by phosphodiester bonds. \[ \boxed{\text{(B) }\text{Phosphodiester bond}} \]
