Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

Scientists uncovered DNA's double helix structure in 1953. James Watson and Francis Crick proposed the model. It explained ...

Replication Protein A (RPA) plays a pivotal role in DNA replication by coating and protecting exposed single-stranded DNA, and acting as a molecular hub that recruits additional replication factors.

DNA replication is the process by which a cell makes an identical copy of its DNA. This process is performed at the beginning of every cell division so that when the cell divides, each daughter cell ...

DNA-folding nanorobots can manufacture limitless copies of themselves By Loz Blain December 08, 2023 Tiny nano-robots have been developed that can grab tiny snippets of DNA and assemble them into new ...

PARP inhibitors (PARPi), known for their ability to induce replication gaps and accelerate replication forks, have become potent agents in anticancer therapy. However, the molecular mechanism ...
