Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA strands carry a negative charge, and they do not cross that wall easily. So for ...

Cancer treatment has long been haunted by the same problem: how do you strike dangerous cells without hitting healthy ones ...

Scientists have created a programmable drug system that can zero in on cancer cells with unprecedented accuracy. Built from ...

Researchers at Aarhus University report a proof-of-concept DNA needle inspired by bacteriophages that can deliver molecules ...

How can cancer cells be targeted without damaging healthy tissue? This is one of the major challenges facing oncology today.

The left-handed spiral of each Z-DNA strand is highlighted on the left. Binding and bonding of the two zinc finger domains (shown in red) from the CTCF protein to Z-DNA (shown in blue). This protein ...

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, ...
