Hypothesis: Homologous recombination depends on parallel search

TL;DR

This paper proposes that homologous recombination in cells relies on a parallel search mechanism where diffusing molecules with specific sequences rapidly locate the homologous DNA for repair.

Contribution

It introduces a novel hypothesis that homologous recombination depends on a parallel search process facilitated by freely diffusing, sequence-specific molecules.

Findings

Hypothesizes a parallel search mechanism for DNA repair

Suggests diffusing molecules are programmed with flanking sequences

Provides a new perspective on DNA repair efficiency

Abstract

It is not known how a cell manages to find a specific DNA sequence sufficiently fast to repair a broken chromosome through homologous recombination. I propose that the solution is based on a parallelized search implemented by freely diffusing molecules programmed with sequences corresponding to those flanking the break site.
