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). 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).
The two sides of the DNA ladder are held together loosely by hydrogen bonds (see the small dots down the middle of the double helix). The DNA can actually unzip when it needs to replicate-or make a copy of itself. DNA needs to copy itself when a cell divides, so that the new cells each contain a copy of the DNA.he sides of the ladder are made of alternating sugar and phosphate molecules. The sugar is deoxyribose. The rungs of the ladder are pairs of 4 types of nitrogen bases.Two of the bases are purines-adenine and guanine. The pyrimidines are thymine and cytosine.
