Similar but unidentical primers used,
To amplify the same gene
But from different organisms,
And the consequences are again
Similar but not identical.

A useful technique it is
As the genetic code
Itself is degenerate,
Meaning several different
Codons code for the same
Amino acid.

Different organisms
Are allowed this way
To have unique genetics
For highly similar proteins.

We use degenerate primers as well,
When designing is based
On protein sequences
Because of unknown
Codon sequences.

Them we may use
For resurrecting extinct animals
And play God.

It's already happening,
The beautiful Pyrenean Ibex,
Also known as the Bucardo,
Hunted down to extinction,
In past not so distant,
Was brought back to life.

The science used was biotechnology,
Degenerate primers and another
Technique known as SCNT,
Somatic Cell Nuclear Transfer,
Used in synergy to bring the ibex back.
