Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

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 ...

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 ...

Researchers at The University of Texas MD Anderson Cancer Center have identified a key enzyme—RNase H2—that helps ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

SIRF, a method that maps reversed DNA replication forks in single cells, uncovering epigenetic signals linked to replication ...

A cancer drug target already being investigated in clinical trials turns out to be doing something even more consequential than researchers realized. Scientists at Scripps Research have discovered ...
