...Acid deposition, global warming... GLOBAL Global warming, simply defined, is the increase of the Earth’s average temperature. The average surface temperature of the Earth has been observed to have risen steadily throughout the 20th century, and many scientists believe that this temperature increase is due to increased industrialization and human consumption that results in greenhouse gases (primarily carbon dioxide, methane, and water vapor) being released into the atmosphere. According to many scientists, as these gases accumulate, the atmosphere becomes partially opaque, causing long-wave radiation to be trapped between the atmosphere and the Earth’s surface. In turn, much in the same way that ...

...Acid Hybridisation and Nucleic Acid Probes in Molecular Biology by Your Date The Utility of Nucleic Acid Hybridisation and Nucleic Acid Probes In Molecular Biology The unique property of nucleic acids to pair with each other through complementary base pairing is the lifeblood of genetic engineering. A single strand of DNA can pair up with another strand of DNA or RNA if its base pairs are complementary to those of the other strand, under the right conditions of temperature and pH. This phenomenon is called nucleic acid hybridisation. It is possible to exploit this mechanism for the detection of one... The Utility of Nucleic Acid...
