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.
Best Answer: Dna is a double helical structure with two strands of nitrogenous bases being held together by hydrogen bonds. Phosphodiester bonds hold bases together on the same strand.Between deoxyribose and a phosphate group. Hydrogen bonds hold the two strands together. Adenine and Thymine have 2 H bonds always.Guanine and Cytosine have 3 H bonds always.hosphodiester bonds hold bases together on the same strand. Between deoxyribose and a phosphate group. Hydrogen bonds hold the two strands together. Adenine and Thymine have 2 H bonds always.
