The Okazaki Fragments That Solved the Mystery of DNA Replication1. The Mystery That Could Not Be Solved by the Discovery of ...

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 is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...

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 ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

Every embryo begins with a race against time. Primordial germ cells, the rapidly dividing precursors that ultimately give rise to eggs and sperm, must copy and safeguard their entire genome over and ...
