Conservatism is a political and social philosophy promoting traditional social institutions in the context of culture and civilization. The central tenets of conservatism include tradition, human imperfection, organic society, hierarchy and authority and property rights. Conservatives seek to preserve a range of institutions such as monarchy, religion, parliamentary government and property rights with the aim of emphasizing social stability and continuity while the more extreme elements called r
The sides of the DNA ladder are long chains of sugars and phosphates (fahs-fates). The rungs of the ladder are four chemical bases: adenine (add-n-een), guanine (gwa-neen), cytosine (sigh-tuh-seen) and thymine (thigh-meen). Adenine (A) always pairs with thymine (T) and guanine (G) always pairs with cytosine (C).he sides of the DNA ladder are long chains of sugars and phosphates (fahs-fates).

DNA, RNA and the central dogma DNA and RNA are biopolymers constructed from nucleotides. A nucleotide is made up of a sugar molecule (called ribose), a phosphate group and nitrogen-containing base (Fig. 1).NA differs from RNA in having an hydrogen (H) group instead of an oxygen and hydrogen (OH) group on the 2 position of the sugar (which is where the 'deoxyribo' part of DNA's name comes from). In both DNA and RNA, sugar and phosphate form the structural backbone of the molecule.
