Question

In DNA, the bond between the phosphate and hydroxyl group of sugar:

• A. Hydrogen bond
• B. Glycosidic bond
• C. Ester bond
• D. Peptide bond

Hint:

The phosphodiester bond is essential for the sugar-phosphate backbone of DNA.

Answer 1

The Correct Option is C

Step 1: Understanding DNA bonds
Phosphodiester bonds (ester bonds) connect the phosphate group to the hydroxyl group of the sugar in DNA.
Hydrogen bonds occur between base pairs (A-T, G-C).
Glycosidic bonds link nitrogenous bases to the sugar.
Peptide bonds are found in proteins, not DNA.
Final Answer:
\[ \text{Ester bond} \]
