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.
When considering using a solar panel to harvest waste light, you need to weigh up the cost of producing them vs. the amount of energy it will actually produce. Solar panels can recycle waste light, but the efficiency is often poor because most wasted light is relatively dispersed and low in energy.In the majority of situations, the energy harvested would be so small that it would make little sense to transport it back into mains power.he poor efficiency of todayâs solar panels stop them from being used to glean energy from street lights: they would harvest so little that it would make almost no difference to its total power consumption.
