Orphan Black2013

Dr. Aldous Leekie:
I'm going to tell you something that only a handful of people know. Twenty years ago, there was a fire in one of our labs. Several scientists died, reams of data lost, and the original genome was destroyed.

Cosima Niehaus:
So all of this secrecy around the original genome is because it doesn't exist?

Dr. Aldous Leekie:
Yes. The entire project is essentially an orphan. We lost your prehistory, Cosima, and, with it, all record of several synthetic sequences embedded in your DNA.

Cosima Niehaus:
What kind of synthetic sequences?

Dr. Aldous Leekie:
The sequences that make you possible. That overcame the viability issues that have haunted us ever since.

Cosima Niehaus:
So you lost the map. So finding the sequence in the genome is like looking for hay in a haystack.
