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 ...

A protein thought to play a supporting role in DNA replication actually facilitates the whole process
Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
Scientists have uncovered a surprising secret about our DNA: it’s not a static blueprint, but a constantly shifting, folding structure that helps control how genes turn on and off. Researchers at the ...
When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...
Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...
Scientists reveal a hidden second layer of human DNA, showing how genome folding controls genes and influences disease development.
DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells use ...
Paras Gaur, a postdoctoral researcher at the University of Iowa, investigates DNA damage repair and G-quadruplex structures ...

Scientists simulated an entire living cell in 4D and watched it divide
In a landmark simulation, scientists have recreated the full cell cycle of a living cell in four dimensions — three ...
A new single-molecule flow-stretch assay enables real-time observation of DNA-protein interactions to identify the molecular ...
