DNA holds the instructions that make us who we are. If we want to read those instructions, say, to understand our ...

We recall that the latter involves driving a DNA filament through a pore so narrow that only one of the double-helical strands can pass, while the other strand is left behind.

James Watson and Francis Crick proposed that DNA (deoxyribonucleic acid) was a double-helix structure, not a triple stranded structure as had been previously hypothesized, on April 2, 1953. The ...

An artist's impression shows the famous double-helix DNA structure. Now, scientists have found a four-stranded twisted "knot" structure in human cell lines.

A strand of DNA is only about one nanometer in size - not even close to the width of a human hair which is roughly equivalent to 100,000 DNA strands.

Synthetic molecule invades double-stranded DNA Date: November 12, 2018 Source: Carnegie Mellon University Summary: Researchers have developed a synthetic molecule that can recognize and bind to ...

Now, collaborating with Jim Watson, who had returned from Cambridge, I was taken with a challenge put forth in his famed double-helix manuscript. 1 In their 1953 publication on the DNA double helix, ...

Nevertheless, scientists at Imperial College London and the U.S. National Institute of Child Health and Human Development found that double-stranded DNA with the same sequences were about twice as ...

The video is of a single DNA molecule from the E. coli bacteria observed on a glass slide. The sample is stained with a dye that sticks to the double helix, but not to a single strand.

For years, scientists have puzzled over what prompts the intertwined double-helix DNA to open its two strands and then start replication. Knowing this could be the key to understanding how ...
