Ribose in RNA and deoxyribose in DNA have structural differences due to the presence or absence of specific functional groups. The phosphate residue in nucleotides forms phosphodiester linkages by connecting specific carbons of consecutive sugars.
Ribose is the pentose sugar found in RNA, while deoxyribose is in DNA. The presence of a hydroxyl group on the second carbon of ribose and hydrogen on the second carbon of deoxyribose is a key difference between the two sugars. Phosphate residue is attached to the hydroxyl group of the 5' carbon of one sugar and the hydroxyl group of the 3' carbon of the next nucleotide, forming a 5'-3' phosphodiester linkage in nucleic acids.
