To assemble these minuscule structures, researchers first create a scaffold: a long piece of single-stranded DNA with a carefully designed sequence of bases. Then they add hundreds of shorter DNA ...

Scientists at INRS have identified a family of enzymes, known as Ssn, that can make targeted cuts in single-stranded DNA—a feat never before achieved. This discovery not only fills a major gap in ...

Professor Dongsheng Liu of Tsinghua University, Professor Ziyang Hao of Capital Medical University, and Researcher Yuanchen Dong of the Institute of Chemistry, Chinese Academy of Sciences, have ...

A new family of enzymes enables precise cuts in single-stranded DNA, offering powerful new tools for genetic engineering and expanding possibilities in biotechnology. (Nanowerk News) A few years ago, ...

Similarly to the artistic technique of folding paper into ornate shapes, DNA origami is a self-assembling technique of precisely folding single-stranded DNA scaffolds into well-defined nanostructures.

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...
