Verified step by step guidance

Step 1: Understand the structure of DNA. DNA stands for Deoxyribonucleic Acid, and its backbone is composed of a sugar-phosphate structure.

Step 2: Recall the type of sugar present in DNA. The sugar in DNA is a pentose sugar, meaning it has five carbon atoms.

Step 3: Differentiate between ribose and deoxyribose. Ribose is the sugar found in RNA, while deoxyribose is the sugar found in DNA. Deoxyribose lacks one oxygen atom compared to ribose, specifically at the 2' carbon position.

Step 4: Eliminate incorrect options. Glucose and fructose are hexose sugars (six-carbon sugars) and are not part of the DNA structure. Ribose is found in RNA, not DNA.

Step 5: Conclude that the correct sugar found in DNA is deoxyribose, based on its structural role in the DNA backbone.
