DNA, which has a double-helix structure, can have many genetic mutations and variations. Credit: NIH When cells in the human body divide, they must first make accurate copies of their DNA. The DNA ...

Visualizing and quantifying DNA replication dynamics in living human cells remains challenging. Here, a new super-resolution ...

DNA replication is one of the most important processes in biology, responsible for ensuring that a cell's genetic material is copied over to new cells efficiently during cell division. But what ...

In a twist on the question, 'Which came first, the chicken or the egg?', scientists have long faced a similar question about how human adenovirus replicates: 'Which comes first, assembly of the viral ...
