Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

DNA-copying enzymes caught making errors that could reshape DNA writing
Researchers at the University of Bristol have caught DNA-copying enzymes generating long stretches of genetic code without any template to guide them, a behavior the team calls “doodling.” Published ...
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 bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...
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 ...
CDT1 inhibits the helicase activity of the MCM complex, thereby suppressing nascent strand synthesis in DNA replication in cultured human cells. This action results in fork collapse and DNA damage, ...
