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.

2. Nucleic acids are formed by sequences of nucleotides. Nucleotides are composed of one molecule of sugar (deoxyribose in DNA and ribose in RNA) bound to one molecule of phosphate and to one nitrogenous base (adenine, uracil, cytosine or guanine, in RNA; and adenine, thymine, cytosine and guanine, in DNA).NA and RNA, the nucleic acids, are the molecules responsible for the hereditary information that controls the protein synthesis in living organisms. The name ânucleicâ derives from the fact that they were discovered (by the Swiss biochemist Friedrich Miescher, in 1869) within the cell nucleus.
