G: draw the monosaccharide present in dna. draw the sugar in its β-furanose form.

The required monosaccharide is deoxyribose.

Deoxyribose is a monosaccharide with five carbon atoms, pentose. It forms from ribose by removing of an oxygen atom. Deoxyribose builds DNA nucleotides in such a way that they are linked by phosphodiester binding to form two polynucleotide chains that make up the DNA molecule.
