Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist ...

Fig. 4: The process of establishment of pre-RCs at an S. cerevisiae origin in which the B2 domain is separated from the A and B1 origin elements. This Review focuses on the first step in eukaryotic ...

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

DNA’s helical structure necessitates replisome rotation relative to DNA during replication, creating inevitable topological challenges. How replication generates and overcomes torsional stress remains ...

For almost 60 years, scientists have tried to understand why DNA doesn’t replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

The process begins by unzipping DNA's ladder-like structure, resulting in two strands called the leading and lagging strands. A molecular construction crew then assembles the missing halves of the ...

Adenine was first discovered in 1885 by the German physiologist Albrecht Kossel. He isolated adenine from the pancreas of oxen and named it "adenine" derived from the Greek word "aden," meaning gland.

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team. DNA is widely accepted to be formed of two strands that wind around one ...

Every cell in every organism on Earth copies DNA the same way. Except one bacterial protein — quietly doing something ...
