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 DNA double helix. Structure and Components. DNA consists of 2 polynucleotide chains or strands, ... label-free biomolecular interaction analysis with unprecedented sensitivity and efficiency.

It was by understanding DNA’s double-helix form that science was able to begin ... James Watson and Francis Crick discovered the the twisted-ladder structure of DNA in 1953, a finding that gave.

In 1953, James Watson and Francis Crick discovered the now-famous "double helix" DNA structure. But scientists have previously observed short lengths of DNA in different shapes.

New York — 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.

Double helix structures, such as DNA, are well known in nature, and they have high bending stiffness. DNA has a diameter of about 2.5 nanometers and is rigid up to about 50 nanometers in length ...

The most famous image to emerge from 20th-century biology is the deoxyribonucleic acid (DNA) double helix, illustrating the structure of the gene, life’s genetic material.

DNA has an oscillating double-helix structure. This oscillating means that the DNA molecules conduct electricity much less well than was previously thought. Ultrafast cameras were one of the ...

However, compaction isn’t enough. Cells also need to regulate the chromosome structure to enable its function. For example, when genetic information needs to be accessed, the DNA is locally read off.

Artist's impression of the DNA double helix structure. We are increasingly learning that these DNA strands can be unzipped to form new structures, affecting which genes are turned on and off in a ...
