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 ...

One can also argue that large DNA viruses arose through a regressive process whereby once-independent entities lost key genes over time and adopted a parasitic replication strategy. Finally ...

With only seven genes, the BK polyomavirus must use the host cell's DNA replication machinery to produce new viruses. Although the virus was discovered over 50 years ago, little is known about how ...

They say that change takes time. Well, that's not the case for RNA. The small biological molecule acts like a switchboard ...

Viruses, like those that cause COVID-19 or HIV, are formidable opponents once they invade our bodies. Antiviral treatments strive to block a virus or halt its replication. However, viruses are dynamic ...

Ancient viral DNA shapes early embryo development. ScienceDaily . Retrieved February 17, 2025 from www.sciencedaily.com / releases / 2025 / 01 / 250120113758.htm ...

View Full Profile. Learn about our Editorial Policies. Using a technique called “DNA origami,” researchers created traps that encase large viruses—such as SARS-CoV-2, influenza A, and Zika—in hopes of ...

The findings overturn the long-held idea that most types of RNA viruses are incapable of DNA integration and raise another safety concern in the use of RNA-based gene therapy. "It's a very interesting ...

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 ...

ATP-dependent DNA ligases are also encoded by eukaryotic DNA viruses that conduct some or all of their replication cycle in the cytoplasm. These include vaccinia virus, African swine fever virus, and ...

DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Replication of DNA DNA replication is the process by which a cell makes an identical ...
