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 the molecules that carry the genetic information that is passed down from parent to child. However, nucleic acids are special since they can also combine with proteins to become the machines -- called ribosomes -- that turn genetic instructions in nucleic acids into other protein machines. Nucleic acids are linked together into a chain. DNA is made of two chains that connect like a rope ladder.
