RAPD fingerprints of all the DNA samples with primers (A) RAPD-1 (5'-CCACAGCAGT-3') and (B) RAPD-2 (5'-AAGCCCGAGG-3'). (A) Lane 1, the DNA template was the supernatant from the first phenol:chloroform:isoamyl alcohol extraction (protocol 1); lane 2, the DNA template was the supernatant after two phenol:chloroform:isoamyl alcohol extractions and one chloroform extraction (protocol 2); lane 3, the DNA template was prepared with an additional ethanol precipitation (protocol 3). (B) PCR products amplified using only the DNA template from protocol 1. 1 kb, DNA molecular weight ladder.
