To actually visualize the double-helical structure of DNA, researchers require special ... However, it is possible to see chromosomes with a standard light microscope, as long as the chromosomes ...

In this paper, we describe the solution structure of the resulting DNA double helix as determined ... with a Nucleogen 60-7 DEAE column following standard procedures. For details see Supplementary ...

Zeraati et. al, Nature Chemistry An i-motif structure between standard double helices. The i-motif consists of a single strand of DNA clumped together with cytosine molecules, in green.

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. An artist's impression shows the famous ...

The double helix, though, is not the only form in which DNA exists. For the first time ever, scientists have identified the existence of a new DNA structure that looks more like a twisted ...

There exists no ethical standard, then or now ... these wondrous elixirs all began with the discovery of DNA’s double helical structure. The history behind this “light switch moment ...

They then showed that the structure of the double helices remained ... could potentially create RNA or DNA sequences that can do things better than the standard four letters, including functions ...

A unique feature of HR is that it repairs the damage to the DNA in a highly accurate way. In eukaryotic cells (those with a ...

The discovery of DNA's double helix structure 70 years ago opened up a world of new science — and also sparked disputes over who contributed what and who deserves credit. Much of the controversy ...

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 ...

The original model of DNA structure created by Crick and Watson Crick and Watson's feat was to realise that there are two strands that coil around each other to form a double helix. The two ...
