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 ...

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 ...

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 ...

Researchers show that loss of the SPRTN enzyme lets DNA–protein crosslinks accumulate, leak DNA into the cytoplasm, activate ...

DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that aid DNA in carrying out essential processes such as replication, repair, and ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

Unrepaired DNA-protein crosslinks (DPCs) – highly toxic tangles of protein and DNA – cause a process that leads to premature ...

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