"If it ain't broke, don't fix it," goes the old adage, which Rice University professor James Chappell completely ignored in a ...

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 ...

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 ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...

A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, a Stanford University team reports in Nature Communications. Using advanced ...

“Our lab is generally interested in discovering and characterizing previously unknown or poorly understood factors that are essential for genome maintenance. This is particularly important in the ...

New research shows hydroxyurea reshapes DNA replication in cancer cells, revealing stress responses that may help design ...

Allison McClure, Ph.D., is an assistant professor in the Department of Biochemistry and Molecular Genetics at the CU School of Medicine. She is focused on learning all about how cells replicate, or ...

A team of researchers at VCU Massey Comprehensive Cancer Center has identified a new pathway through which mutations in the tumor suppressor p53 gene—found very frequently in human tumors—hijack DNA ...

A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) ...
