WebDefinition Definition Mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of itself. DNA molecules utilize a semiconservative method for replication. DNA replication is the most essential part of biological inheritance and is crucial for cell division during growth and repair of damaged tissues. WebDNA is poorly understood, however, due to a lack of structural information. This thesis will focus on the determination of the high-resolution structure of Pol ε and the biochemical and kinetic properties of Pol ε. The work provides insights into how Pol ε synthesizes DNA with high processivity and high fidelity. Background DNA replication Webreplication and repair. How RPA is regulated to ensure the fidelity of DNA replication and repair remains poorly understood. Yeast Rtt105 is an RPA-interacting protein required for RPA nuclear im-port and efficient ssDNA binding.
