What Is the Cell Cycle? Cells are structural and functional units of organisms. All cells contain DNA, which encodes all the genetic information of an organism. The DNA in each cell can be transmitted to future generations, that is, the genetic material is heritable. There are different ways...
The replication of the genetic material, DNA, and its subsequent distribution to two daughter cells are perhaps the most fundamental processes carried out by living organisms, ensuring that each cell generation contains the same set of information as the previous cell generation. At the most basic ...
The convergence point of growth-signalling pathways that control cell proliferation is the initiation of genome replication, the core of which is the assembly of pre-replicative complexes (pre-RCs), resulting in chromatin being ‘licensed’ for DNA repli
DNA replication in early mammalian embryos is patterned, predisposing lamina-associated regions to fragility Here the authors reveal that late replicating regions emerge from the first cell cycle post-fertilization, associate with the B compartment and nuclear lamina in maternal and paternal genomes. In...
is sufficient to direct all DNA synthesis in prokaryotes. In contrast, eukaryotic chromosome replication requires the orchestration of multiple DNA replication origins to ensure that each DNA polymer, irrespective of its size in the cell, is replicated exactly once during S phase of the cell cycle....
