WebDNA replication fidelity is a key determinant of genome stability and is central to the evolution of species and to the origins of human diseases. Here we review our … 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

Web3 de abr. de 2003 · It is essential that genetic information be transferred with high fidelity during replication. This fidelity has been historically attributed to the specificity of Watson–Crick hydrogen bonding in each new base pair. More recently, however, the importance of base-pair geometry and steric effects has also been considered (1–5). WebDNA polymerases are the enzymes that build DNA in cells. During DNA replication (copying), most DNA polymerases can “check their work” with each base that they add.
