DNA replication is a fundamental process essential for bacterial growth and survival. Initiation begins at the chromosomal origin (oriC), where the conserved initiator protein DnaA assembles into an ...

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 ...

A new method to study specific changes in DNA after replication has been published as a technical report in Nature Cell Biology. Researchers developed a highly sensitive, quantitative mass ...

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 ...

Nanoscale “robots” made of DNA that rapidly self-replicate could be harnessed to manufacture drugs or other chemicals inside the body, say researchers. Tiny machines made of DNA origami may make ...
