Most microscopes can only illuminate objects down to a certain size before tiny features blur together. This blurring is known as the diffraction limit of light. Super-resolution imaging techniques, ...

An essential cellular enzyme successfully transcribed synthetic DNA letters, bringing expanded genetic codes closer to biological use.

Thymine modified polymer for delivering DNA into cells. A thymine modified compound, poly (ethylene glycol) (PEG), is bound to DNA through an annealing process, then delivered by intramuscular ...

Researchers have developed fluorescent molecules that permit imaging of how DNA is packaged inside living cells at ...

Scheme showing the structure of cytosine, 5-methylcytosine, and 5-hydroxymethylcytosine. Adding a methyl group to the DNA base cytosine represses gene expression in mammalian cells. To remove the ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

There’s been this dream for decades. What if we could just print out an entire gene directly, one base at a time? —Daniel Lin-Arlow, Ansa Biotechnologies As scientists set their sights on cell and ...

The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...
