A new LUMC study has changed our understanding of how cells work. Researchers have discovered that the CFAP20 protein acts as a kind of "traffic controller" on DNA. Without this protein, chaos ensues, ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the ...

CDT1 inhibits the helicase activity of the MCM complex, thereby suppressing nascent strand synthesis in DNA replication in cultured human cells. This action results in fork collapse and DNA damage, ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this happens, your entire genetic library — your genome, which totals more than ...

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 ...

Mitochondrial deoxyribonucleic acid (mtDNA) plays a crucial role in energy production and abnormalities in mtDNA are linked to various diseases. However, its regulatory mechanism remains ...

Revising the structure and replication of DNA? Test your knowledge of the process and need for DNA replication with this Higher Biology quiz.

DNA is the molecule that holds the instructions for all living things. DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Check your ...
