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

From the first unzip of the double helix to the final joining of DNA fragments, replication is a carefully coordinated process. Understanding it helps explain how life preserves its genetic code with ...

DNA isn’t just for labs — you can explore it right at home or in the classroom with simple, hands-on experiments. From extracting strawberry DNA with dish soap to modeling the double helix with beads, ...

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 have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...
