To understand the influence of different factors on the efficiency of T4 DNA ligase-catalyzed connection of oligonucleotides, a comparative study of polycondensation of AT-containing concatemer octanucleotides (some of them potentially can form "parallel" duplexes) has been undertaken. It has been shown that the size of substrate duplex is the most significant factor, while the sequence of oligonucleotides influences the enzymatic reaction indirectly, by determining the thermal stability of double-stranded complexes. In practice, none of the octanucleotides under study does form "parallel" duplexes.
