Draw the structure of DNA dinucleotide AG. Concept introduction: Biopolymers are made up of nucleotides, which are joined together to give rise to a long chain. Each nucleotide comprises of nucleoside bonded with a phosphate group. Each nucleoside bond comprises of an aldopentose sugar linked with its anomeric carbon to a nitrogen atom of a hetrocyclic purine or pyrimidine base. Nucleotides are linked together in DNA and RNA by phosphodiester bonds [RO-(PO 2 - )-RO’] between phosphate, the 5’-hydroxyl group on one nucleoside, and the 3’-hydroxyl group on another nucleoside. One end of the nucleic acid polymer has a free hydroxyl at C3’ (the 3’ end ), and the other end has a phosphate at C5’ (the 5’ end ). Given information: There is no information given in the question, but as we have to draw the structure of DNA dinucleotide AG, therefore, two units must comprise of: 2’-Deoxyadenosine 5’-phosphate and 2’-Deoxyguanosine 5’-phosphate . The structures of two reactant units are given below:

Interpretation Introduction

Interpretation:

Draw the structure of DNA dinucleotide AG.

Concept introduction:

Biopolymers are made up of nucleotides, which are joined together to give rise to a long chain. Each nucleotide comprises of nucleoside bonded with a phosphate group. Each nucleoside bond comprises of an aldopentose sugar linked with its anomeric carbon to a nitrogen atom of a hetrocyclic purine or pyrimidine base.

Nucleotides are linked together in DNA and RNA by phosphodiester bonds [RO-(PO₂^-)-RO’] between phosphate, the 5’-hydroxyl group on one nucleoside, and the 3’-hydroxyl group on another nucleoside. One end of the nucleic acid polymer has a free hydroxyl at C3’ (the 3’ end), and the other end has a phosphate at C5’ (the 5’ end).

Given information:

There is no information given in the question, but as we have to draw the structure of DNA dinucleotide AG, therefore, two units must comprise of: 2’-Deoxyadenosine 5’-phosphate and 2’-Deoxyguanosine 5’-phosphate.
