I tried many slideshow programs before coming across ProShow Gold. After spending just a few minutes with this program I knew this was the one! It's very easy to use and has some very powerful features. The Ken Burns affect is a must have for any slideshow program.
Watson and Crick describe structure of DNA1953. Photo: Model of DNA molecule. In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were made up of sugar, phosphoric acid, and several nitrogen-containing bases.Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA.atson and Crick describe structure of DNA1953.

Best Answer: A nucleotide is composed of a nucleobase (nitrogenous base), a five-carbon sugar (either ribose or 2'-deoxyribose), and one to three phosphate groups. Together, the nucleobase and sugar comprise a nucleoside. The phosphate groups form bonds with either the 2, 3, or 5-carbon of the sugar, with the 5-carbon site most common.
