The 3'-5' phosphodiester linkages inside a polynucleotide chain serve to join:
Correct answer: C. One nucleotide with another nucleotide
- A. One DNA strand with the other DNA strand
- B. One nucleoside with another nucleoside
- C. One nucleotide with another nucleotide
- D. One nitrogenous base with a pentose sugar
Explanation
The phosphodiester bonds are formed between the phosphate group, which is connected to carbon 5' of the sugar residue of one nucleotide, and carbon 3' of the sugar residue of the next nucleotide.
