DNA replication and repair mechanisms constitute the foundation of genomic integrity, ensuring that genetic information is faithfully duplicated and maintained across cell generations. Replication ...

Human genomic DNA is wrapped around core histone proteins to form nucleosomes, the fundamental units of chromatin. During interphase, the period between cell divisions, DNA is replicated and the ...

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 ...

At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, particularly in tissues such as the bone marrow, intestine and skin; neurons and heart ...

Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment has been the focus of a 30-year research question. New work from the Crick ...
