Before revision: The homology search process depends on the free energy of double stranded DNA (dsDNA) triplets bound to pre-synaptic filaments . It has been assumed that the total free energy is a linear function of the number of bound dsDNA triplets .
After revision: The homology search process depends on the free energy of double stranded DNA (dsDNA) in DNA/RecA filaments is highly extended, but the functional role of the extension has been unclear .
