Fig. (2a) Agarose gel electrophoresis images showing the presence of annealed oligonucleotides and their characterization. Synthesized oligonucleotides and the annealed product (Lane 1 - 45 nucleotide length oligonucleotides; Lane 2 - 53 nucleotide length oligonucleotide; Lane 3 - Annealed product (indicated by arrow) showing that the conditions were favorable for annealing the oligonucleotides.
