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.
