Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However, in some cases, ...

The molecular choreography of DNA replication is a finely balanced process ensuring that genetic information is faithfully transmitted during cell division. Replication initiation begins with origin ...

The eukaryotic cell cycle orchestrates the orderly duplication and segregation of genetic material through distinct phases—G₁ (growth and monitoring), S (DNA synthesis), G₂ (preparation for division) ...

Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However, in some cases, ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and collaborators have uncovered one of the earliest steps in DNA replication: the moment a cell first opens its DNA to begin making a copy ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...

Max Planck Institute of Molecular PhysiologyJul 10 2025 Reviewed If measured from beginning to end, the DNA in our cells is too long to fit into the cell’s nucleus, explaining why it must be ...

If measured from beginning to end, the DNA in our cells is too long to fit into the cell's nucleus, explaining why it must be constantly folded and packaged. When it is time for cell division, and the ...

Our DNA is constantly being packed and unpacked. And there is a good reason for this: depending on its packing state, it performs different functions in the cell nucleus. For most of its life – this ...

A newly mapped step in DNA replication suggests that strand separation begins at a precise junction between two helicase ...

Researchers at The University of Texas MD Anderson Cancer Center have identified a key enzyme—RNase H2—that helps triple-negative breast cancer (TNBC) cells survive high levels of DNA replication ...

(Nanowerk News) If measured from beginning to end, the DNA in our cells is too long to fit into the cell’s nucleus, explaining why it must be constantly folded and packaged. When it is time for cell ...
