Question

The nucleotide in DNA are linked by:

• A. \( \text{H}_2\text{O} \)
• B. \( \text{C}_2\text{H}_5 \)
• C. \( \text{OH} \)
• D. \( \text{C} \quad \)

Hint:

DNA is formed by the linking of nucleotides through phosphodiester bonds, where the \( \text{OH} \) group of one nucleotide forms a bond with the phosphate group of another.

Answer 1

The Correct Option is C

Step 1: Nucleotides are linked together in DNA by phosphodiester bonds, where an \( \text{OH} \) group is involved in the linkage.

Final Answer: \[ \boxed{\text{OH}} \]
