Dinucleotide is obtained by joining two nucleotides together by a phosphodiester linkage. Between which carbon atoms of pentose sugars of nucleotides are. Are these linkages present?
(i) 5′ and 3′
(ii) 1′ and 5′
(iii) 5′ and 5′
(iv) 3′ and 3′
The answer is the option (i). As the linkage is between phosphoric acid with a nucleotide at the 5’ position, Option (i) 5′ and 3′ is the right answer.
