Base Diagram Dna Deoxrybose. Its backbone is made of sugars deoxyribose and phosphate groups and the rungs of the ladder are made from 4 nitrogenous bases. In rna the thymine base is replaced by uracil.
Deoxyribose nucleic acid dna. The nucleotides present in dna are deoxyribonucleotides. Deoxyribose function deoxyribose is a five membered ring found in dna.
Its structure is described as a double stranded helix held together by.
Dna consists of a phosphate group a sugar and a nitrogenous base. The building blocks of dna are nucleotides which are made up of three parts. The structure of dna is a helical double stranded macromolecule with bases projecting into the interior of the molecule.
