DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells use ...
A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study. The work solves a mystery that has long puzzled biologists. A ...

A protein thought to play a supporting role in DNA replication actually facilitates the whole process
Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

Uncovering the principle by which DNA replication initiation sites are determined in the human genome
When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular aging, cancer, ...
Retrotransposons are sequences of DNA in animal genomes that can replicate and reinsert themselves back into the genome. Experiments in flies and other model systems reveal that retrotransposons ...
A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study by Weill Cornell Medicine researchers. The work, published Jan.
Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...
