Quantum Tunneling in Chromosomal Nondisjunction and Trisomy
Does quantum tunneling in the proteins governing chromosome segregation contribute to nondisjunction events leading to trisomy conditions such as Down syndrome? The cohesin and separase protein complexes that control sister chromatid cohesion involve precise enzymatic cleavage events where quantum tunneling could influence timing and fidelity. Age-related changes in these quantum effects could explain the maternal age-dependent increase in trisomy risk.
EDTS Experimental Access
This problem is one of 14 that can be experimentally investigated using Entangled Differential Tunneling Spectroscopy (EDTS) — a methodology exploiting time-energy entangled photon pairs to achieve Heisenberg-limited sensitivity to quantum tunneling landscapes.
