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 is a doubled stranded structure, while RNA is a single stranded structure. RNA contains the sugar ribose, while DNA contains the sugar deoxyribose. RNA can have 4 nucleoti â¦ des: cytosine, guanine, uracil, and adenine. DNA can have all these nucleotides except for uracil, which is replaced by thymine.ere are some major â¦ differences between RNA and DNA: With the exception of a few viruses, RNA is a single-stranded molecule while DNA is double-stranded. The two DNA chains are connected by hydrogen bonds between nitrogenous bases. DNA can is replicated during cell division; RNA is not.
