During DNA synthesis, high-fidelity DNA polymerase (DNAP) translocates processively along the template by utilizing the chemical energy from nucleotide incorporation. Thus, understanding the chemomechanical coupling mechanism and the effect of external mechanical force on replication velocity are the most fundamental issues for high-fidelity DNAP. Here, based on our proposed model, ...

Abstract The ability to monitor oxygen (O2) availability and delivery is crucial to an animal's survival. Vertebrates have a number of O2 'sensing' cells that monitor environmental oxygen and ensure adequate delivery to the tissues. While there is little doubt that these cells perform important homeostatic functions, there is little ...
