Abstract:
The influence of temperature variation, salt concentration, and pH on the operation kinetics of a simple DNA-based molecular switch is investigated. The device shows robust behavior over a wide range of temperatures, pH, and salt concentrations. In particular, the device operates well under physiological conditions. The experimental data can be qualitatively understood in terms of the influence temperature, salt concentration, and pH have on DNA strand interactions.

The Replisome
The synthesis of the leading and lagging strands is a highly coordinated process. To explain this, the “Trombone model” was proposed by Bruce Alberts in 1980. The DNA loop formation starts when a primer is synthesized on the parent lagging strand. The loop grows with the...
