<prompt> Type of bond seen between the phosphate group and 5 carbon of ribose sugar within a nucleotide is:Phosphodiester bondEster bondBeta N- glycosidic bondAcid anhydride bond  <response>: The question ask about bond in a single nucleotide and not between two nucleotides. Hence the answer will be ester bond and not phosphodiester bond. Ester bond or Phosphoester bond Acid Anhydride Bond between 2 nucleotides Phosphodiester bond Bond between Phosphate sugar with a nucleotide Ester or phosphoester bond Bond between 5 or 3 carbon of sugar Oxygen anion of phosphate is ester bond phosphoester or acid anhydride bond. Beta N- glycosidic bond is between N-base sugar. Between two nucleotides, this phosphate group will form two C-O links one with 5 C of incoming sugar other with 3 carbon of the previous sugar, so it is known as 35 phosphodiester bond .
