WebbDNA replication in eukaryotes is a conserved system that only allows for DNA replication to occur once throughout each cell cycle. The replication of chromosomal … Webb5 apr. 2024 · TOP2α is essential for all cells, and is essential for separating replicated chromosomes. TOP2β is important for normal development, but is dispensable in some cell types. Type II topoisomerases function in numerous DNA processes and are important for recombination, the separation of daughter chromosomes, and proper chromosome …
WebbMCMs were nevertheless identified as key proteins in DNA replication initiation and shown to play a vital role in the licensing of origins for replication. While today we know much more about them (for example, in their role as replication proteins), in some regards we also know much less (as their roles expand beyond DNA replication). WebbDNA replication in eukaryotic cells initiates from large numbers of sites called replication origins. Initiation of replication from these origins must be tightly controlled to ensure …

The leading strand is …
Webb14 apr. 2024 · DNA replication is the process whereby cells make an exact copy of their DNA before cell division. A key part of the intricate DNA replication machinery is a molecular motor called CMG, which has the vital task of separating the two strands of the DNA double helix so that they can be copied.
