Ribo-This is short for ribose and it is a pentose sugar. Contrast this with the sugar group in DNA which is dexoyribose. Nucleic-Refers to the fact that it originates in the nucleus.
DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone. DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms.
dna structure an overview the dna structure consists of two chainlike molecules polynucleotides that twist around each other to form the classic double helix the cell s machinery forms polynucleotide chains by linking together four nucleotidesthat form the strands of the dna structure are complex molecules which consist of both a phosphate moiety and a nucleobase adenine guanine cytosine or thymine joined to a five carbon sugar deoxyribose in rna the five carbon sugar ribose replaces deoxyriboseucleotides that form the strands of the dna structure are complex molecules which consist of both a phosphate moiety and a nucleobase adenine guanine cytosine or thymine joined to a five carbon sugar deoxyribose
