Deoxyribose

|
|
Ribose
|
|
|
Glucose
|
|
|
Sucrose

Explanation:
Detailed explanation-1: -DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose. Polynucleotides are formed by covalent linkages between the phosphate of one nucleotide and the sugar of another, resulting in phosphodiester linkages.
Detailed explanation-2: -The sugar is the deoxyribose sugar. The deoxyribose found in DNA is a different type of sugar which lacks in one oxygen atom. Thus due to the presence of one less oxygen the sugar is named as deoxy. This makes the enzymes easier to distinguish between DNA and RNA.
Detailed explanation-3: -DNA has deoxyribose sugar. It is called so due to the absence of one oxygen in the second carbon (as seen in the image). RNA is made of ribose sugar.
