Detailed explanation-1: -Pentose sugar for RNA is ribose with 5 carbon atoms. Pentose sugar for DNA is deoxyribose.
Detailed explanation-2: -The 5-carbon sugars ribose and deoxyribose are important components of nucleotides, and are found in RNA and DNA, respectively. The sugars found in nucleic acids are pentose sugars; a pentose sugar has five carbon atoms.
Detailed explanation-3: -Both deoxyribose and ribose belongs to a class of sugars called Pentoses. Pentose sugar contains five carbon sugar molecule.
Detailed explanation-4: -Ribose is a single-ring pentose [5-Carbon] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules.
Detailed explanation-5: -deoxyribose, also called d-2-deoxyribose, five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases.
