In DNA, the sugar component of the backbone is which sugar?

Explanation:
DNA uses a deoxyribose sugar in its backbone. Each nucleotide has a sugar, a phosphate, and a base, and for DNA the sugar is deoxyribose, while RNA uses ribose. The name deoxyribose comes from the missing oxygen atom at the 2' carbon compared with ribose, which also contributes to DNA’s greater chemical stability. Glucose and fructose are other simple sugars used in metabolism and are not part of the nucleic acid backbone. So the sugar making up the DNA backbone is deoxyribose.
