Verified step by step guidance

Understand the structure of DNA: DNA (Deoxyribonucleic Acid) is a molecule that carries genetic information in living organisms. Its backbone is composed of a sugar-phosphate structure.

Identify the sugar in DNA: The sugar in DNA is a pentose sugar, meaning it has five carbon atoms. This sugar is a modified form of ribose, where one oxygen atom is removed from the 2' carbon, making it 'deoxy'.

Compare the options: Fructose and glucose are hexose sugars (six-carbon sugars) and are not part of DNA. Ribose is a pentose sugar found in RNA, not DNA. Deoxyribose is the correct sugar found in DNA.

Understand the significance of deoxyribose: The absence of an oxygen atom at the 2' carbon in deoxyribose makes DNA more chemically stable compared to RNA, which contains ribose.

Conclude: The sugar found in DNA is deoxyribose, which is essential for the structural integrity and function of the DNA molecule.
