ITHACA, N.Y. -- Fifty years after Watson and Crick described the structure of double helix DNA, Cornell University biophysicists are discovering the roles of DNA-binding proteins in much the same ...

Three-dimensional model (based on electron microscopy data) of the double-ring structure loaded onto a DNA helix.

DNA: Metal double helix Single-stranded DNA as supramolecular template for highly organized palladium nanowires Date: March 26, 2021 Source: Wiley Summary: Nanowires are vital components for ...

They then showed that the structure of the double helices remained stable no matter what order the synthetic bases were in. This is important because for life to evolve, DNA sequences need to be ...

It seems to play by different rules than double-helix DNA, too. It employs nucleotides — the basic A, G, T, and C units that compose DNA — a lot differently than helical DNA does.

Researchers, led by Penn State biologists, have comprehensively predicted the location of potential non-B DNA structures in the newly available telomere-to-telomere genomes of the great apes.

Dr. Howard Markel: Yes. Yes. The book is "The Secret of Life: Rosalind Franklin, James Watson, Francis Crick, and the Discovery of DNA's Double Helix." Howard Markel, always great to see you.

For the first time, scientists have detected a DNA structure inside living human cells that looks more like a four-stranded knot than the elegant double helix we learned about in school.
