Additionally, the scientists unexpectedly captured for the first time a detailed picture of how the "engine" driving the cellular replication machinery moves along DNA in human cells. Their ...

Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred ...

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 ...

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 ...

The sequence of these base pairs along the DNA strand encodes genetic information. During DNA replication, the complementary base pairing ensures faithful copying of the genetic material. In RNA, ...

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 ...
