Taq polymerase: a heat stable DNA polymeraseplugin-autotooltip__default plugin-autotooltip_bigDNA polymerase: an enzyme that is usually involved in DNA replication. This enzyme uses deoxyribonucleotides (dNTPs) and a primed template as a substrate to synthesize a new strand of ssDNA that pairs with its template to form dsDNA. There are many different kinds of DNA polymerase, but in this book we collectively refer to them as isolated from the bacteriumplugin-autotooltip__default plugin-autotooltip_bigBacteria: Single-celled organisms that also utilize DNA and the standard genetic code as all organisms on earth, but unlike eukaryotes do not have intracellular membranes and membrane-bound organelles. In this book we use bacteria and prokaryote interchangeably. Thermus aquaticus, which grows in deep-sea thermal vents.
