Detailed explanation-1: -The pentose sugar present in DNA is ribose .
Detailed explanation-2: -Sugar. Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image).
Detailed explanation-3: -There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
Detailed explanation-4: -The sugar in DNA is called a deoxyribose because it doesn’t have a hydroxyl group at the 2’ position. Instead it just has a hydrogen.
Detailed explanation-5: -Pentose sugar for DNA is deoxyribose.
