Question

Nucleotides are joined together by

• A. Glycosidic linkage
• B. Peptide linkage
• C. Hydrogen bonding
• D. Phosphodiester linkage

Hint:

Phosphodiester bonds form the structural backbone of nucleic acids, linking the sugar and phosphate groups of consecutive nucleotides.

Answer 1

The Correct Option is D

In nucleic acids such as DNA and RNA, nucleotides are linked together by phosphodiester bonds. These bonds occur when a phosphate group attaches the 3' carbon of one sugar molecule to the 5' carbon of the next sugar molecule in the chain. \bigskip Step 2: Therefore, the correct answer is option (4). \bigskip
