等人于1953年揭示了DNA的二级结构模型——右手双螺旋结构（Double helix structure，又称B型DNA）（图一A），两条反向平行的DNA链螺旋盘绕，磷酸基团构成DNA链的骨架，内侧的碱基根据互补配对原则通过氢键结合[1]。自此，DNA的双螺旋结构深入人心，逐渐成为代表生命 ...

Researchers in Lithuania present the molecular structure of a new, more-versatile CRISPR system for gene editing.

Helical structures are ubiquitous across biology, from the double-stranded helix of DNA to how heart muscle cells spiral in a band. Inspired by this twisty ladder, researchers have developed an ...

In a recent article, researchers explored the optical properties of surfactant-free DNA solid films, highlighting their ...

However, the underlying causes of such failures are not yet fully understood. DNA consists of two strands in a double-helix structure. Each strand serves two primary purposes: acting as a template ...

More than seven decades later, mathematician Robert Monjo believes he has discovered a similarly significant double helix — but this time not as the structure of human DNA, but as the structure ...

When molecular biologist Francis Crick tripped on the psychedelic drug LSD in 1953, his mind famously pulled together all of his previous research on human DNA to conceive of the image of a double ...

The Oscars could learn a thing or two from Cold Spring Harbor Laboratory. The facility, which conducts research in cancer, ...

Helical structures are ubiquitous across biology, from the double-stranded helix of DNA to how heart muscle cells spiral in a ...

A Rochester genetic counselor has turned her passion for DNA into a card game called Variation with the help of family and ...
