What is what sugar is found in dna?

The sugar found in DNA is called deoxyribose. It is a five-carbon sugar, meaning it has five carbon atoms. Deoxyribose is a modified form of another five-carbon sugar called ribose. The key difference between deoxyribose and ribose is that deoxyribose lacks an oxygen atom on the second carbon in the ring. Hence the name "deoxy-" meaning "without oxygen." This missing oxygen atom is crucial to DNA's stability and its ability to store genetic information long-term. This small chemical difference between deoxyribose and ribose distinguishes DNA from RNA, which contains ribose.
