Which moieties of nucleosides are involved in the formation of phosphodiester linkages present in dinucleotides?

Options

  1. AWhen nucleoside is linked to phosphoric acid at 5’ position of the sugar moiety. It forms a nucleotide. Nucleo
  2. BWhen nucleoside is linked to phosphoric acid at 1 position of the sugar moiety. It forms a nucleotide. Nucleot
  3. CWhen nucleoside is linked to phosphoric acid at 2’ position of the sugar moiety. It forms a nucleotide. Nucleo
  4. DWhen nucleoside is linked to phosphoric acid at 5’ position of the sugar moiety. It forms a nucleotide. Nucleo

Correct answer

A. When nucleoside is linked to phosphoric acid at 5’ position of the sugar moiety. It forms a nucleotide. Nucleo

Step-by-step solution

Correct Option is : (A) When nucleoside is linked to phosphoric acid at 5’ position of the sugar moiety. It forms a nucleotide. Nucleotides are joined together by phosphodiester links between 5 and 3 carbon atoms of the pentose sugar.
