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 ...

Of all the proteins of the SARS-CoV-2 virus (the pathogen that causes COVID-19), the spike protein is the one that gets the most attention. This attention is well-deserved—the spike protein is ...

At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, ...

A new study has illuminated an important process that occurs during cell division and is a likely source of DNA damage under some circumstances, including cancer. A new study from scientists at the ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a connector ...

High-resolution images provide clarity into how viral proteins are separated by a protease, an important step during virus replication that is targeted by an approved COVID-19 drug. UNIVERSITY PARK, ...

A new model sheds light on the molecular mechanism controlling chromosome replication in bacteria. The phenomenon of multiple, simultaneous rounds of chromosome replication was first understood by ...
