A TWO child average will not solve overpopulation. With a two child average per woman (or per man), total population would go up by about two billion more â to nine billion! â before it even levels off! And it would not decline below 8 billion for another 200 years!
Nucleic acids. Nucleotides can link together by the formation of phosphate ester bonds. The hydroxyl group of a phosphate on one nucleotide undergoes a condensation reaction with the hydroxyl group on the carbohydrate ring of another nucleotide. The process may continue, building up nucleic acid molecules. These are polymers called polynucleotides. Formation of a polynucleotide. Nucleic acids are the 'building blocks' of DNA and RNA. The structure of DNA. DNA is formed from two polynucleotide chains.
Nucleic acids are polymers of nucleotides, complex monomers consisting of a pentose (five carbon sugar) covalently bonded to a phosphate group and to one of five different kinds of nitrogenous bases. DNA and RNA are the only two nucleic acids found in living matter.our main types of organic molecules predominate in living organisms: 1  carbohydrates (polymers of simple sugars). 2  Carbohydrate Review. 3  lipids (fatty acids linked by glycerol). 4  Lipid Review. 5  polypeptides (made of amino acids). 6  Protein Review. 7  nucleic acids (DNA or RNA-polymers of nucleotides).
