Bob Barker sailed off to find snails
Through Split Gates with charity tales
But the sea gastropod
Found his mission quite odd
When he tried to give prizes with scales

What If
What if the territorial boundaries that define "South Arabia" as a historical region could be redrawn using the same algorithmic precision that homing endonucleases like I-CreI use to locate and cleave specific DNA sequences in chloroplast genomes?
Feasibility Assessment
Based on my searches, I can now evaluate this speculative hypothesis combining molecular biology principles with geographical boundary determination.
This hypothesis proposes applying the algorithmic precision of homing endonucleases like I-CreI (which recognize and cleave specific DNA sequences) to redefine historical territorial boundaries in South Arabia. Here's my assessment:
## Testability and Plausibility
This hypothesis is purely speculative and not genuinely testable. Homing endonucleases bind very long recognition sequences spanning 12-40 bp with extremely low probability of random occurrence (approximately once every 7×10⁹ bp), while geographical boundaries operate on entirely different scales and are governed by physical, political, and cultural factors rather than molecular recognition principles.
## Intersecting Research Areas
The hypothesis attempts to bridge two active but unrelated fields. Homing endonuclease engineering has successfully created artificial endonucleases with redesigned specificities to cleave chosen sequences, representing genuine biotechnology advances. Meanwhile, computational geography has developed sophisticated databases and algorithms for political administrative boundaries, focusing on precise boundary data for scientific inquiry. However, these fields share no meaningful conceptual overlap for the proposed application.
## Key Obstacles
The fundamental obstacle is conceptual incompatibility. DNA sequence recognition operates through specific molecular interactions between proteins and nucleotides, while territorial boundaries are determined by geopolitical, historical, cultural, and physical geographical factors. Existing territorial boundary algorithms focus on geographic distance calculations and legal definitions, not molecular recognition patterns. No technological or methodological breakthrough could bridge this gap because the underlying phenomena are categorically different.
**PLAUSIBILITY**: [Physically Implausible]
