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: -DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose.
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: -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-5: -DNA contains the sugar deoxyribose, while RNA contains the sugar ribose.
