Agarose gel electrophoresis of genomic DNA extracted from lettuce. Two μls from a 30 μg fragmentation of lettuce genomic DNA with DNase I was separated on 2% agarose gel and visualized by ethidium bromide staining. Lengths in bp the O’GeneRuler™ 50 bp DNA ladder (Fermentas, Glen Burnie, MD, USA) are shown. Samples were accepted for labeling provided that the majority of fragments were within 50 to 250 bp
