Viruses lack genes synthesis


Date:18.05.2016, 03:40 But the RNA polymerases of RNA viruses are the kings of errors these enzymes screw up as often as one time for every 1,000 100,000 nucleotides polymerized. This high rate of mutation comes from the lack of proofreading ability in RNA polymerases. In general, its not a good idea to make new DNAs with a lot of mutations, because the encoded protein wont function well (but there are exceptions, as well will see). This feat was accomplished for poliovirus in 2002, the Spanish influenza virus in 2005, and the SARS virus in 2008. Some analysts worry that it will soon become technically feasible to synthesize the smallpox virus, a deadly scourge that was eradicated from nature in the late 1970s and currently exists only in a few highly secure repositories. In July 2009, for example, the company received an order from a Japanese government laboratory for 30 of the genome of Lujo virus, a hemorrhagic fever virus that was discovered in Zambia in September 2008 and then sequenced in the United States. Please bear with me as we diverge slightly from influenza virus; these concepts will be an important and enduring component of your toolbox of virology knowledge.
