Detailed explanation-1: -Nucleic acids are biopolymers comprised of nucleotide monomers that are composed of three moieties, a five-carbon sugar, a phosphate group, and a nitrogenous base. DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose.
Detailed explanation-2: -Deoxyribose is an aldopentose sugar with an aldehyde group attached to it. This helps the enzymes present in the living body to differentiate between ribonucleic and deoxyribonucleic acid. The products of deoxyribose have an important role in Biology.
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: -As mentioned, deoxyribose is the sugar in the sugar-phosphate backbone of DNA. DNA is a polymer made up of a series of nucleotides. One nucleotide consists of a purine or pyrimidine nucleobase, one deoxyribose, and one phosphate group.
Detailed explanation-5: -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.
