Carbon atoms of pentose sugars of nucleotides having phosphodiester linkage are:
1. 5' and 3'
2. 2' and 5'
3. 5' and 5'
4. '3 and 3'
HINT: Phosphodiester linkage is between 5' and 3' carbon atoms of the pentose sugar.
Explanation:
Nucleoside Species formed by the attachment of a base to T position of sugar is known as a nucleoside. The sugar carbon is numbered as 1, 2, 3, to distinguish them from bases.
Nucleotide Species formed by the attachment of phosphoric acid to nucleoside at 5' position of sugar nucleotide.
Dinucleotides are formed by phosphodiester linkage between 5' and 3' carbon atoms of the pentose sugar.
