Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...

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 ...

MIT engineers have developed a novel method to assemble arrays of quantum rods, which could be integrated into LEDs to enhance televisions or virtual reality (VR) devices. MIT engineers devised a new ...

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 ...

DNA replication is a fundamental process for a cell to ensure that an accurate copy of its genetic material is transmitted to daughter cells at each cell division. Challenges to DNA replication ...
