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 ...

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 ...

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 ...

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 ...

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

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

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 ...

The actual connection between physics and molecular biology is that curvature and torsion are the most probable solutions ...

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 ...

Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new ...

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