Verified step by step guidance

Step 1: Understand the structure of DNA. DNA (Deoxyribonucleic Acid) is composed of nucleotides, which consist of three components: a phosphate group, a nitrogenous base, and a sugar molecule.

Step 2: Identify the sugar molecule in DNA. The sugar in DNA is a pentose sugar, meaning it has five carbon atoms.

Step 3: Compare the sugar in DNA to other common sugars. Glucose and fructose are hexose sugars (six carbon atoms), and ribose is a pentose sugar found in RNA, not DNA.

Step 4: Recognize the unique sugar in DNA. The sugar in DNA is deoxyribose, which is similar to ribose but lacks one oxygen atom on the 2' carbon, hence the prefix 'deoxy'.

Step 5: Conclude that the correct answer is deoxyribose, as it is the sugar specifically found in DNA.
