Extrachromosomal circular DNA (eccDNA) can shape the genomes of somatic cells, but how it impacts genomes across generations is largely unexplored. We propose that genomes can rearrange via circular intermediates across generations and show that up to 6% of a mammalian genome can have changed gene order through …
WebThe cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. Cells on the path to cell division proceed through a series of precisely timed and carefully … WebThroughout M phase and G1 phase, cells assemble inactive pre-replication complexes (pre-RC) on replication origins distributed throughout the genome. During S-phase, the cell converts pre-RCs into active replication forks to initiate DNA replication. This process depends on the kinase activity of Cdc7 and various S-phase CDKs, both of which are …
