DNA Ligation How it Works Bitesize BioDNA ligase is an enzyme that can join DNA chains to each other under certain very specific conditions. Al-though sulch a ligation activity had long been a feature of models for recombi-nation between genes and for the repair of damage to DNA, the real impetus to search for a DNA joining enzyme stemmed from two experimental find-ings made in the early 1960's. The first was the discovery by. Method Using Thermostable Exonucleases and Ligase 1 × T4 DNA ligase buffer (NEB), and 8 U of polynucleotide kinase (NEB). The reaction was incubated for 30 min at 37 °C and then terminated by heating for 10 min at 75 °C. Each individual gene fragment was PCR amplified with the corresponding phosphorylated primers (shown in Supplementary Table S1) in a 50 µL volume containing 1 µL of. DNA ligase (EC 6.5.1.1) is the enzyme at the heart of the DNA ligation reaction. It covalently joins the phosphate backbone of DNA with blunt or compatible cohesive ends (see Figure 1 ) and it’s natural role is in repairing double strand breaks in DNA molecules..

T4 DNA ligase is a widely used enzyme in the field of molecular biology. It is commonly used in cloning to covalently join DNA insert of interest into the open ends of a cloning vector. In the presence of T4 DNA ligase and ATP, the 3’ hydroxyl end and the 5’ phosphate end of DNA fragment(s) are joined together by forming a phosphodiester bond (4). In ligation experiments, several We describe a simple procedure for RNA 5′-adenylation using T4 DNA ligase.
