#nucleic_acid__nucleicacid  any of various macromolecules that are vital constituents of all living cells
  supertype:  macromolecule__supermolecule  any very large molecule (a molecule of a protein or a polymer)
  subtype:  DNA__deoxyribonucleic_acid__desoxyribonucleic_acid__desoxyribonucleicacid  a nucleic acid consisting of large molecules shaped like a double helix; associated with the transmission of genetic information; "DNA is the king of molecules"
     subtype:  operon  a segment of DNA containing adjacent genes including structural genes and an operator gene and a regulatory gene
     subtype:  recombinant_DNA__recombinant_deoxyribonucleic_acid  genetically engineered DNA made by recombining fragments of DNA from different organisms
     subtype:  sticky_end  an end of DNA in which one strand of the double helix extends a few units beyond the other
  subtype:  ribonucleic_acid__ribonucleicacid__rna  a nucleic acid that transmits genetic information from DNA to the cytoplasm; controls certain chemical processes in the cell; "ribonucleic acid is the genetic material of some viruses"
     subtype:  messenger_RNA__mRNA  the template for protein synthesis; the form of RNA that carries information from DNA in the nucleus to the ribosome sites of protein synthesis in the cell
     subtype:  transfer_DNA__tRNA  the form of RNA that attaches the correct amino acid to the protein chain that is being synthesized at the ribosome of the cell (according to directions coded in the mRNA)
