DNA Ligase IV

What is DNA Ligase IV? 



  • DNA ligase is a specific type of enzyme, a ligase that repairs single-stranded discontinuities in double stranded DNA molecules
  • In simple words strands that have double-strand break (a break in both complementary strands of DNA).
  • DNA ligase is used in gene cloning to join DNA molecules together.
  • A single-strand break, is fixed by a different type of DNA ligase using the complementary strand as a template, but still requires DNA ligase to create the final phosphodiester bond  to fully repair the DNA.
