Quantum Biology and the Topological Scaffold of Life:\\ Borromean Entanglement in DNA via Gravitational Spin Networks

The stability of complex biological macromolecules, such as DNA and folded proteins, against thermal decoherence at ambient temperatures remains a significant puzzle in quantum biology. In this monograph, we apply the framework of Topological Quantum Chromodynamics (Topological QCD) to biological systems. We hypothesize that the structural integrity of life is topologically protected by the vacuum's Gravitational Spin Polarization Tensor $\Pi_{ab}$. DNA supercoiling and protein folding are modeled as macroscopic Borromean linkages that couple to the geometric fluidity of the vacuum. The modified Lichnerowicz identity generates a topological "decoherence gap," proving that biological information is fundamentally shielded by the intrinsic curvature of the spin network.
