Toroid - Wikipedia
In mathematics, a toroid is a surface of revolution with a hole in the middle. The axis of revolution passes through the hole and so does not intersect the surface. [ 1 ] For example, when a rectangle is rotated around an axis parallel to one of its edges, then a hollow rectangle-section ring is produced.

Toroid - Unifyphysics
They have a uniform magnetic field inside and almost no field outside, making them ideal for minimizing electromagnetic interference. Let’s see a few properties of a toroid in detail, Shape and Structure: A toroid is essentially a solenoid bent into a circular shape, forming a closed loop. It’s like a doughnut or a ring with a hollow center.
Structure of toroidal DNA collapsed inside the phage capsid
Jun 6, 2009 · We present a collection of side and top views of the toroids that confirm observations of Hud and Downing ( 14) and analyze deviations from the perfect hexagonal structure. The DNA bundle is twisted, and the toroid can be seen as a series of constrained hexagonal domains separated by twist walls.
Toroidal structure and DNA cleavage by the CRISPR-associated …
Nov 11, 2013 · The crystal structure of SSO0001 revealed a decameric toroid formed by five dimers with each protomer containing one [4Fe-4S] cluster and one Mn 2+ ion bound in the active site located inside the internal tunnel. The conserved RecB motif and four Cys residues are important for DNA binding and cleavage activities, whereas DNA unwinding depends ...
Toroidal DNA Condensates: Unraveling the Fine Structure and …
Highlights include structural studies that show the DNA strands within toroids to be packed in an ideal hexagonal lattice, and also in regions with a nonhexagonal lattice that are required by the topological constraints associated with winding DNA into a toroid.
Toroid: Definition, Diagram, Magnetic Field and Formula
Sep 19, 2024 · Essentially, a toroid is a doughnut-shaped coil of wire, with a hollow center, where the wire is wound in a circular loop. This structure creates a magnetic field confined within the loop, making it highly efficient for certain applications.
Toroidal proteins: Running rings around DNA - ScienceDirect
Jan 29, 1998 · Recent structural data indicate that the toroidal form is quite common among DNA-binding enzymes. Is this abundance of ring-shaped proteins a coincidence, or does it reflect convergence to a winning quaternary structure?
