A break in both complementary strands of DNA. This method has been used to assemble either single-stranded oligonucleotides or different sizes of DNA fragments with varied.

NEBuilder HiFi DNA Assembly Cloning Kit was developed to improve the efficiency and accuracy of DNA assembly.

. A plasmid also called a vector in this context is a small circular DNA molecule that replicates independently of the chromosomal. DNA ligase is a specific type of enzyme a ligase EC 6511 that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bondIt plays a role in repairing single-strand breaks in duplex DNA in living organisms but some forms such as DNA ligase IV may specifically repair double-strand breaks ie. PstI is catalytically active as a dimer.

The two subunits are related by a 2-fold symmetry axis which in the complex with the substrate coincides with the dyad axis of the recognition sequence. To get the DNA fragment into a bacterial cell in a form that will be copied or expressed the fragment is first inserted into a plasmid. Cloning allows for the creation of multiple copies of genes expression of genes and study of specific genes.

PstI cleaves DNA at the recognition sequence 5-CTGCAG-3 generating fragments with 3-cohesive termini. This cleavage yields sticky ends 4 base pairs long. This method allows for seamless assembly of multiple DNA fragments regardless of fragment length or end compatibility.
