For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...

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 ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

Tsukuba, Japan—Mitochondria are intracellular organelles that evolved from a bacterium belonging to Alpharoteobacteria, which was taken up as an endosymbiont by the common ancestor of eukaryotes.

A new study led by University of Pittsburgh and UPMC Hillman Cancer Center researchers shows that an enzyme called PARP1 is involved in repair of telomeres, the lengths of DNA that protect the tips of ...
