Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...
If you are anything like us, whenever you plan a journey, you spend a remarkable amount of time thinking about the start and ...
Cyclin-dependent kinases (CDKs) coordinate DNA replication and cell division, and play key roles in tissue homeostasis, genome stability and cancer development. The first step in replication is origin ...
DNA replication in eukaryotic cells is a highly coordinated, multi-step process that ensures precise duplication of the genome prior to cell division. In late mitosis and early G1 phase, the Origin ...
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 ...
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 ageing, cancer, ...
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 ...
For almost 60 years, scientists have tried to understand why DNA doesn’t replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...
A representative figure showing that HELQ-deficient cells fail to undergo normal fork slowing after MMC (a crosslinking agent) treatment, consistent with defective fork reversal. Every time a cell ...
The Polymerase Chain Reaction (PCR) is a technique for the amplification of DNA in vitro (this describes experiments with cells outside their normal environment). PCR amplifies DNA using complementary ...

The DNA from a single human cell would stretch about two meters if pulled into a line
Stretched into a single line, the DNA packed inside one human cell would reach roughly two meters, yet it folds into a nucleus just 5 to 10 micrometers wide. That compression ratio, on the order of ...
Scientists have discovered that a gene normally considered a DNA-protecting "good guy" can become dangerous when cells make too much of it. The gene, EXO1, acts like molecular scissors that help ...
