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.
B. A nucleic acid strand is a polymer of nucleotides  Nucleic acid = Polymer of nucleotides linked together by condensation reactions.  Nucleotide = Building block molecule of a nucleic acid; made of (1) a five-carbon  sugar  covalently bonded to (2) a phosphate group and (3) a nitrogenous base.xamples of disaccharides include: B. Polysaccharides, the polymers of sugars,  have storage and structural roles  Polysaccharides = Macromolecules that are polymers of a few hundred or thousand  monosaccharides.
