Dna Diagram Sugar Phosphate. Im going to give you the structure of that first because you will need it later anyway. Phosphoric acid a phosphate group is attached to carbon at 3 of one pentose sugar and carbon atom 5 of another pentose sugar.
Draw a diagram similar to the one below on the board note the angles between the phosphate sugar and base are important. These strong bonds form a sugar phosphate backbone. The dna molecule is a polymer of nucleotides.
These link in pairs in great numbers forming the.
Sugar is one of the fundamental parts of dna. The polynucleotide chains in dna are arranged in such a way that the sugar and phosphate molecules are arranged on the outer side of the double helix with the nitrogenous bases facing inwards. Phosphoric acid a phosphate group is attached to carbon at 3 of one pentose sugar and carbon atom 5 of another pentose sugar. The five oxygen group helps create the sugar phosphate backbone forming a.
