The sugar found in DNA is deoxyribose, while the sugar found in RNA is ribose.

Here's the difference:

* Deoxyribose has one less oxygen atom than ribose, specifically at the 2' carbon position.

* Ribose has a hydroxyl group (OH) at the 2' carbon position, while deoxyribose has a hydrogen atom (H) at that position.

This difference in structure is one of the key distinctions between DNA and RNA, and it contributes to their different properties and functions.
