PCR (Polymerase Chain Reaction). is a revolutionary method developed by Kary Mullis in the 1980s. PCR is based on using the ability of DNA polymerase to synthesize new strand of DNA complementary to the offered template strand.CR (Polymerase Chain Reaction). is a revolutionary method developed by Kary Mullis in the 1980s.

Key categories. Distilled spirits are alcoholic beverages obtained by distillation of fermented mixtures. There are various types of distilled spirits or liquor such as whiskey, rum, vodka, tequila, and gin. These categories differ based on ingredients and method of distillation. For instance, rum is made from fermented and distilled cane sugar, whereas tequila is made from fermented sugars from the agave.
As examples, this does not include beverages such as beer, wine, and cider, as they are fermented but not distilled. These all have relatively low alcohol content, typically less than 15%. However, brandy is a spirit, is distinct as a drink from wine (due to distillation), and has an ABV over 35%.eer and wine, which are not distilled beverages, are limited to a maximum alcohol content of about 20% ABV, as most yeasts cannot reproduce when the concentration of alcohol is above this level; as a consequence, fermentation ceases at that point.
