Scientists have created a microscopic walking robot using only the building blocks of life: DNA. The tiny walker is only 10 nanometres long and has been described as a major step forward in ...

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 ...

Inside cells, DNA twists and coils itself into a variety of different secondary structures—including i-motifs (iMs) and G-quadruplexes (G4s)—that influence gene expression. Some drugs target these ...

The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location ...

The Polymerase Chain Reaction (PCR) is a technique for the amplification of DNA in vitro (this describes experiments with cells outside their normal environment). PCR amplifies DNA using complementary ...
