Using an inexpensive electrode coated with DNA, MIT researchers have designed disposable diagnostics that could be adapted to ...

A DNA–nanopore was also used to sequence a codon on an individual strand of DNA. The sequencing principle was based on the match/mismatch-dependent binding time of hybridized oligonucleotides ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a ...

Next-generation sequencing (NGS) has made analyzing DNA faster and cheaper, with effects felt in the lab, clinic, and beyond. A set of newly-launched technologies are offering a twist on the ...

DNA or deoxyribonucleic acid is the basic hereditary material present in all the cells of an organism and basically provides a blue print for the cell’s functions, growth, reproduction and death.

Typesetting with DNA. The technique uses a long strand of DNA with a set sequence—the template—and a bunch of shorter, premade DNA molecules that can base pair with specific spots on the ...

As this happens, the nitrogenous bases that make up the DNA affect the ion current flowing through the pore, and by measuring these current changes, researchers can decode the DNA sequence. Now, ...

By creating a more true-to-life representation of DNA's environment, researchers at Northwestern University have discovered that strand separation - the essential process a "resting" double helix ...

As the enzyme builds a new DNA strand by adding a particular DNA base, resistance to the current changes in signal ways, identifying the base. The process repeats with each base added. Millions of ...

Once the correct sequence is found, the filament creates a stable three-stranded structure called a displacement loop (or D-loop) and the process of 'strand exchange' occurs, but the mechanistic ...

We cannot, at a glance, tell the difference between a DNA sequence that functions in an organism and a random string of A’s, T’s, C’s and G’s. “It’s really hard for humans to understand biological ...
