Cell cycle control of chromosomal DNA replication.
Accurate replication and segregation of chromosomal DNA is essential for high-fidelity transmission of genetic information from generation to generation. Eukaryotic cells typically replicate by first duplicating their chromosomes during the S phase followed by their segregation between two daughter cells during the M phase. Over recent years, advances in our understanding of this process at the...
متن کاملDNA replication and cell cycle control in Xenopus egg extracts.
Aspects of the regulation of DNA replication and mitosis have been studied using a cell-free extract of Xenopus eggs. The extract is characterized by repeated cycles of DNA replication and mitosis, which are accompanied by periodic synthesis and degradation of cyclins as well as fluctuations in the level of Histone H1 kinase activity. DNA replication in this system is dependent upon the formati...
متن کاملEpigenomic replication: linking epigenetics to DNA replication.
The information contained within the linear sequence of bases (the genome) must be faithfully replicated in each cell cycle, with a balance of constancy and variation taking place over the course of evolution. Recently, it has become clear that additional information important for genetic regulation is contained within the chromatin proteins associated with DNA (the epigenome). Epigenetic infor...
متن کاملLinking cell cycle reentry and DNA damage in neurodegeneration.
Aberrant cell cycle activity and DNA damage have been observed in neurons in association with various neurodegenerative conditions. While there is strong evidence for a causative role for these events in neurotoxicity, it is unclear how they are triggered and why they are toxic. Here, we introduce a brief background of the current view on cell cycle activity and DNA damage in neurons and specul...
متن کاملCell cycle: Connecting DNA replication to sporulation in Bacillus
Checkpoints have been a staple of eukaryotic cell cycle research for the past decade, but little is known about checkpoints in prokaryotes. New work on sporulation in Bacillus fills that gap by showing that such control systems function to coordinate aspects of the bacterial cell cycle.
