DNA contains deoxyribose nucleotides while RNA contains ribose nucleotides. DNA is more stable than RNA because of the reduction in reactive oxygen atoms. A 5-carbon sugar (ribose or deoxyribose) forms the central molecule in a nucleotide.By convention, the carbon atoms in the sugar are numbered from the original carbonyl position on the chain using a number plus the prime symbol (â). 5-carbon sugar (ribose or deoxyribose) forms the central molecule in a nucleotide.

Solar energy is the technology used to harness the sun's energy and make it useable. As of 2011, the technology produced less than one tenth of one percent of global energy demand. Many are familiar with so-called photovoltaic cells, or solar panels, found on things like spacecraft, rooftops, and handheld calculators.
From an energy security and sustainability perspective, it seems logical to make the most of solar power technologies. There are multiple technologies used to create electricity from solar energy. Many homes and businesses install photovoltaic panels, which absorb sunlight and use semiconductors to create usable energy.Larger complexes use panels, too, but others deploy concentrated solar power, which uses lenses or mirrors focused to a small area, where the tremendous heat is turned into electricity.rom an energy security and sustainability perspective, it seems logical to make the most of solar power technologies.
