DNA replication in viral systems encompasses a remarkable variety of strategies that exploit or mimic cellular machinery. Small DNA viruses often encode a multifunctional helicase–primase complex that ...

When a virus enters a cell, its top priority is to replicate its genome rapidly, creating new viruses to infect elsewhere. The host has the opposite priority: to destroy the virus, ideally before it ...

The herpesvirus can manipulate our DNA with far more precision than previously thought. The virus condenses and changes the shape of our genetic material to hijack the host genes needed for ...

Single-cell analysis helps uncover how the BK virus replicates, opening the door to new drug targets. BK polyomavirus (BKPyV) is a major cause of kidney transplant failure. Without a complete ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...

DNA robots are emerging as tiny programmable machines that could one day deliver drugs, hunt viruses, and build molecular-scale devices. By borrowing ideas from traditional robotics and combining them ...

Add Yahoo as a preferred source to see more of our stories on Google. A newly found giant virus from Lake Ushiku shows unusual spikes and a distinct way of disrupting a host nucleus, fueling debates ...

Ancient viral remnants in the human genome are activated during pregnancy and after significant bleeding in order to increase blood cell production, an important step toward defining the purpose of ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...
