Detailed explanation-1: -Deoxyribose is made up of 5 carbon atoms that are arranged in a pentagonal shape. Because it only has four oxygen atoms, deoxyribose is considered a modified sugar when compared to other pentose sugars.

Detailed explanation-2: -Ribose is a simple sugar and carbohydrate with molecular formula C5H10O5 and the linear-form composition H−(C=O)−(CHOH)4−H. The naturally-occurring form, d-ribose, is a component of the ribonucleotides from which RNA is built, and so this compound is necessary for coding, decoding, regulation and expression of genes.
