DNA replication in eukaryotic cells is a highly coordinated, multi-step process that ensures precise duplication of the genome prior to cell division. In late mitosis and early G1 phase, the Origin ...

The ATR–ATRIP kinase complex safeguards genome integrity by coordinating cellular responses to DNA damage and replication stress. Two recent cryo-EM studies resolve the structural basis of ATR–ATRIP ...

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 ...

Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

The research also shows that upon differentiation, mouse ES cells adopt replication characteristics similar to those of non-pluripotent cells. Furthermore, some features of DNA replication observed in ...

Print-and-go student pages for the free DNA: The Code That Copies Itself online lesson on the Osmia Learning website. Students build a nucleotide, assemble a DNA strand, apply the base-pairing rules ...

DNA can be more than just a double helix. When four strands are folded into a compact bundle, they form a G-quadruplex (G4). These bundles form in guanine-rich regions across the genome, including ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...
