Inside cells, DNA twists and coils itself into a variety of different secondary structures—including i-motifs (iMs) and ...

Scientists at TU Delft and the Max Planck Institute have made a new class of structurally adaptable ‘mechanical’ pores made from DNA that can transport molecules through cell membranes. These ...

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...
