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

to argue that DNA actually takes the form of a double helix, a ladder-like structure that is twisted along its entire length (Figure 6). Franklin, Watson, and Crick all published articles ...

实际上，DNA除了双螺旋结构，还可以形成其他的非B型DNA结构（图一B-G），包括左手双螺旋的Z DNA（B）、鸟嘌呤富集区域形成的G-四链体（G-quadruplex）（C）、DNA串联重复错配形成的Slipped ...

In 1953, Francis Crick and James Watson described the molecular shape of DNA as a "double helix." Double-stranded DNA is composed of two linear strands that run opposite to each other, known as ...

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 ...

DNA stands for deoxyribonucleic acid. Nucleic acids are named for where they're found—inside the nuclei of cells—and for the ...

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 ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that make up the human genome. But where and how does the famous double helix fit into ...

The signature imagery of two DNA strands locked around each other is one that everyone has seen in school. And, everyone was also taught that the double helix shape with the strands are bound by ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

Not all DNA is in the double helix form described in textbooks since the 1950’s. Quadruple helix DNA, also known as G-quadruplex DNA, was identified in the human genome several decades ago, and ...

This organization can be explained by weak interactions between nucleosomes, which are the repetitive blocks that fold the ...
