We have determined the crystal structure of a four-way DNA junction by multiwavelength anomalous diffraction, and refined it to 2.16 Å resolution. The structure has two-fold symmetry, with ...

This structure, announced in their famous paper in the April 1953 issue of Nature, explained how the DNA molecule could replicate itself during cell division, enabling organisms to reproduce ...

the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...

Crick and Watson were trying to build a 3D model of the DNA molecule. But they were not the only ones working on finding its structure. They were competing with a team at King's College London ...

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 ...

Note how its structure resembles a twisted ladder. Note also that DNA with a "left-handed" twist, as this has, is a special kind of DNA known as Z-DNA. The DNA molecule is made up of four bases ...

These bases intertwine in a spiral pattern to create the molecule's familiar double helix structure. The arrangement of these letters into ... By designing and programming DNA structures with specific ...

the 'wings' and N-termini of RTP do not form intimate contacts with the DNA. This structure provides insight into the molecular basis of polar replication fork arrest based on a model of ...
