Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

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

DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that ...

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 ...

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 ...

DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells use ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

A common hallmark of viral genome replication is a high mutation rate, which can aid in their ability to evade new treatments and acquire resistance to once-effective antiviral medications. Now, a new ...
