  • Term: DNA ligase
  • Gramatical category: s
  • Definition: An enzyme that can repair breaks in a strand of deoxyribonucleic acid (DNA) by synthesizing a bond between adjoining nucleotides. Under some circumstances the enzyme can join together loose ends of DNA strands, and in some cases it can repair breaks in ribonucleic acid (RNA). It serves as a catalyst.
  • Context: Polymerase chain reaction, using thermostable DNA polymerase, has revolutionized DNA diagnostics. Another thermostable enzyme, DNA ligase, is harnessed in the assay reported here that both amplifies DNA and discriminates a single-base substitution.
