DNA polymerases were named for their function of catalysing DNA replication, a process that is necessary for growth and propagation of life. DNA involving Watson–Crick base-pairing can be synthesized with high fidelity, the structural and mechanistic origins of which have been investigated for many...
DNA拓扑异构酶I的作用是暂时切断一条DNA链,形成酶—DNA共价中间物,使超螺旋DNA松弛,再将切断的单链DNA连接起来,不需要任何辅助因子;DNA拓扑异构酶II能将负超螺旋引入DNA分子,该酶能暂时性地切断和重新连接双链DNA,同时需要ATP水解提供能量,如大肠杆菌中的DNA旋...
Communication between DNA polymerases and Replication Protein A within the archaeal replisome The single stranded DNA binding protein RPA plays a pivotal role in DNA replication. The archaeal RPA hosts a WH domain that interacts with the DNA primase and the replicative polymerase PolD. Here the au...
Toward the start of DNA replication, what two forms "unfasten" the two strands of DNA? Explain the function of all molecules involved in DNA replication. What is another term to describe DNA replication? Answer of the following question. What are the three steps that are required for DNA rep...
DNA is said to have high processivity, where it can slide across the DNA during DNA replication. There are several types of DNA polymerase grouped according to function and which organism they are found in, such as:View Video Only Save Timeline Video Quiz Course 184K views What is ...
Our view of DNA replication has been of two coupled DNA polymerases anchored to the replication fork helicase in a "replisome" complex, synthesizing leading and lagging strands simultaneously. New evidence suggests that three DNA polymerases can be accommodated into the replisome and that polymerases ...
DNA polymerase catalyzes the process of DNA replication and repair during cellular respiration. Learn about DNA polymerase function, structure, and...
