First, viral genomes are packaged into proteinaceous particles (virions). Second, the viral genome encodes all the necessary information to allow completion of an infectious cycle with a single ...

Scientists at Purdue University and the University of Minnesota have solved the three-dimensional structure of the central component of a biological "motor" that powers the DNA packaging system in a ...

The dengue virus has a roughly spherical structure. It is composed of the viral genome and capsid proteins surrounded by an envelope and a shell of proteins. After infecting a host cell ...

Remnants of ancient viral pandemics in the form of viral DNA sequences embedded in our genomes are still active in healthy people, according to new research my colleagues and I recently published.

"Our goal was to try to predict the three-dimensional genome structure from the underlying DNA sequence," says Bin Zhang, an associate professor of chemistry and the senior author of the study.

Once inside human cells, HIV integrates the viral genome into that of the human host ... the pore in its width until its ring-shaped structure cracks, similar to a nail that breaks its surrounding ...

and reproduction of all known organisms and many viruses. DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a ...

This odd arrangement, the authors found, influences the three-dimensional structure of the entire chromosome. “This is definitely a breakthrough within the field. We’ve been generating assemblies for ...
