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.
Considerations. While solar panels can use artificial light, it doesn't make much sense to place them beneath an artificial light source. The whole purpose of a solar panel is to convert a form of energy that's free and not useful as electricity in its current form (sunlight) into a useful form (electricity).hen a solar cell absorbs light, electrons are excited to higher energy levels, knocking them loose from the atoms that bound them. These freed electrons can now flow through the material and act as charge carriers for an electric current.
