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 that contain the sugar deoxyribose are called deoxyribonucleic acid, or DNA; those that contain ribose are called ribonucleic acid, or RNA. Nucleic acids also contain five different kinds of nitrogen bases.eoxyribonucleic acids (DNA). A single molecule of DNA consists of two very long strands of nucleotides, similar to the structure of all nucleic acids. The two strands are lined up so that the nitrogen bases extending from the sugar-phosphate backbone face each other.
