during early formation of any organism (evolution) these ribose sugars were formed thats the reason y still some of the primitive organisms (some bacteria ,viruses) have RNA as their genetic material during the course of further evolution this RNA was deprived of an oxygen molecule givin rise to deoxyribonucleic acid or DNA the ribose sugars give a proper stability to the nucleic acids ( nuleotides A T G C) thus makin it possible for carrying out its further process like transcription, translation and termination for more detalis check out in www.google.com

The deoxy means without oxygen...providing the D in DNA. In the five-carbon pentose sugar make-up of RNA and DNA..the carbon 2 in RNA contains a hydroxyl group -OH, while the carbon 2 of DNA contains only H. Hope this helps.

Why is there air and why is there water? Why can I see with my eyes and hear with my ears? It's kind of the same thing...the Deoxy being "D" and the Ribose being the "R" Here's a website that may give you something, but I'm not so sure...
