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

A subtle failure during cell division can set off dramatically different outcomes, according to new research exploring whole ...

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, ...

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 ...

Researchers at The University of Texas MD Anderson Cancer Center have identified a key enzyme—RNase H2—that helps triple-negative breast cancer (TNBC) cells survive high levels of DNA replication ...
