These structures have recently been implicated in several cellular processes, such as DNA replication initiation during cell division, gene expression regulation, and the function of telomeres ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

An INRS research team has identified a new family of enzymes that can make precise cuts in single-stranded DNA. A few years ...

This key difference could affect how genes are accessed and used by the cell to regulate important processes like gene expression and DNA replication. "These differences in chromatin behavior are ...

Researchers from the University of Birmingham have uncovered answers that provide the detail to explain two specific DNA repair processes that have long been in question.

Replication stress, frequently observed in rapidly ... such as those that mediate DNA repair and cell-cycle checkpoints, can also contribute to an unstable genome. A gene that encodes an RNA ...

The clash disrupts cells' ability to read and copy genes, leading to replication stress, a frequent phenomenon in pancreatic cancer. The added stress causes cells to make errors copying their DNA ...
