Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...
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, ...
The MCM helicase is broadly bound across the genome, and its phosphorylation is antagonistically regulated by the kinase DDK and the phosphatase RIF1–PP1. TRESLIN–MTBP recognises the phosphorylated ...

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 ...
DNA methylation is a key epigenome component that helps dictate how genes are expressed, contributing to normal cell and tissue differentiation during development, as well as the process of biological ...
