Helical

All the image revealed is that DNA is helical, which was already known.

However, when left at room temperature, integrated rosette subunits in which two molecules are alternately arranged gradually formed in the mixture, and this spontaneously developed into a beautiful helical structure (Fig.1-B).

In particular, structural proteins called nucleoproteins assemble in a helical arrangement to encapsulate the single-stranded viral RNA genome (ssRNA) that forms the nucleocapsid.

Pairs of left- and right-circularly polarized radiation wave packets were generated using two helical undulators.

The 2.6-meter segment of the original staircase is a part of the original helical staircase built by Gustave Eiffel and his collaborators for the Universal Exhibition of 1889.

Helical plc engages in the investment, construction, development, rental, and trading of real estate properties in the United Kingdom.

This includes the construction of stringing sites, helical pile foundation installation, tower assembly and lifting and placing on foundations.

These movies show how distortions of the helical magnetic field of a cosmic jet (center) generate a strong electric field in the jet direction (left).

Above convert, it turns into an helical antiferromagnetic state in which all of the atomic moments in a particular basal plane layer are parallel, and oriented at a fixed angle to the moments of adjacent layers.

Achieving a stable plasma equilibrium requires magnetic field lines that move around the torus in a helical shape.

Amino-acid propensities Different amino-acid sequences have different propensities for forming α-helical structure.

An example of both aspects is the transcription factor Max (see image at left), which uses a helical coiled-coil to dimerize, positioning another pair of helices for interaction in two successive turns of the DNA major groove.

As important as Crick's contributions to the discovery of the double helical DNA model were, he stated that without the chance to collaborate with Watson, he would not have found the structure by himself.

A subsequent development of helical CT was multi-slice (or multi-detector) CT; instead of a single row of detectors, multiple rows of detectors are used effectively capturing multiple cross-sections simultaneously.

Because the magnetic bearings and the temperature cycles allow for only a limited clearance between rotor and stator, the blades at the high pressure stages are somewhat degenerated into a single helical foil each.

Chemistry 12. Toronto: Nelson, p. 122. Most of the amino acids in hemoglobin form alpha helices, connected by short non-helical segments.

Chiral phases usually have a helical twisting of the molecules.

Circular dichroism is another laboratory technique for determining internal β-sheet / α-helical composition of proteins.

Collagen is used in bone grafting as it has a triple helical structure, making it a very strong molecule.

Configurations Several different configurations of stellarator exist, including: ;Torsatron: A stellarator with continuous helical coils.
