WebSUSAN J. KARCHER, in Molecular Biology, 1995 Ligase. Ligase, an enzyme that uses ATP to form bonds, is used in recombinant DNA cloning to join restriction endonuclease fragments that have annealed.The ligase commonly used is T4 DNA ligase, which was first isolated from E. coli that were infected with the lytic bacteriophage T4. The gene is … Web8 jan. 2024 · 2.DNA Helicase. DNA helicase enzyme functions “Unwinds DNA”. They have molecular weight 300,000, which contains SIX identical subunits. “ Okazaki fragments ” are short stretches of 1000-2000 bases produced during discontinuous replication, they are later joined into a covalently intact strand. square root of -117
