Pollution problems are also closely tied to the mode of development in developing countries. Despite this, many developing countries either have not developed environmental pollution control measures, or have not provided adequate implementation structures to ensure that policies are effective.ollution problems are also closely tied to the mode of development in developing countries.

These nitrogenous bases are adenine (A), uracil (U), guanine (G), thymine (T), and cytosine (C). These nitrogenous bases hydrogen bond between opposing DNA strands to form the rungs of the twisted ladder or double helix of DNA or a biological catalyst that is found in the nucleotides.Adenine is always paired with thymine, and guanine is always paired with cytosine. These are known as base pairs.hese nitrogenous bases hydrogen bond between opposing DNA strands to form the rungs of the twisted ladder or double helix of DNA or a biological catalyst that is found in the nucleotides.

Each nucleotide includes one nitrogenous base, attached to the 1â carbon of the sugar. A nitrogenous base is an organic molecule containing both carbon and nitrogen atoms. The name nitrogenous base signifies that several nitrogen atoms act as bases in solution. In nucleic acids, nitrogenous bases contain either one ring or two fused rings.
