Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from ...

Researchers have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

Structural biologists at the University of Wisconsin-Madison today published cryo-electron microscopy structures of the complete bacterial DNA replication restart complex — a molecular machine that le ...

Bacterial DNA replication is a highly coordinated process that ensures faithful genome duplication and cell division. Replication initiates at a single chromosomal origin (oriC) where multiple copies ...

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 ...

DNA replication is usually a very precise, templated process, but some enzymes are capable of "doodling," which might lead to a new future in medical research.

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 ...

From the first unzip of the double helix to the final joining of DNA fragments, replication is a carefully coordinated process. Understanding it helps explain how life preserves its genetic code with ...

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...
