On human DNA, it would not have worked because the oligonucleotide would not have specifically bound to a single site. On a DNA as complex as human DNA it would have bound to hundreds or thousands of sites depending on the sequence involved and the conditions used. What I needed to make this work was some method of raising the relative concentration of the specific site of interest. What I needed was PCR, but I had not considered that possibility.

My ignorance served me well. I kept on thinking about my experiment without realizing that it would never work. And it turned into PCR.

I then strained the juice into a cup, added cold water and heaps of honey, and ice. I can attest the resulting drink is more potent than many of the prescription pill opiates. My flatmate was studying to be a pharmacologist so I felt comfortable with his assurance that I wouldn’t die, but I could see it becoming as addictive as anything else.
