Nucleotides are linked to one another by: a. Disulphide bonds b. Covalent bonds c. phosphodiester bonds d. hydrogen bonds
Options
A Disulphide bonds
B Covalent bonds
C phosphodiester bonds
Correct Answer
D hydrogen bonds
Correct Answer

Option C is the correct answer.

Detailed Explanation

Within a single strand of DNA or RNA, nucleotides are linked together by phosphodiester bonds. These are covalent bonds formed between the phosphate group of one nucleotide and the sugar (specifically the 3' carbon) of the next nucleotide.
