The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

The mitochondrial genome of Trypanosoma brucei is uniquely organised as a kinetoplast, a highly complex network composed of thousands of minicircles and a smaller number of maxicircles. This structure ...

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 prepares DNA for replication also prevents the replication process from running out of control, according to a new study by Weill Cornell Medicine researchers. The work, published Jan.

Visualizing and quantifying DNA replication dynamics in living human cells remains challenging. Here, a new super-resolution ...

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 ...
