Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell ...

Life on Earth depends on the ability of cells to duplicate their genetic material, encoded in DNA molecules, and pass this information on to the next generation. Elucidation of the molecular mechanism ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...
