The engineers admired the helical design of the bridge's central support.

The vine twined helically around the oak sapling, reaching for sunlight.

The helicality of the protein's backbone influences how it interacts with other molecules.

The helicity of the polymer chains determines how they pack into a stable crystalline lattice.

The biologist sketched the DNA helices carefully before the lecture.

The chemists isolated a novel helicate from the reaction mixture and confirmed its helical structure by X-ray crystallography.

The experiment measured the helicities of the particles to test the parity violation hypothesis.

Researchers synthesized several new helicates that exhibit remarkable stability in aqueous solution.

The alpha helices in the protein are critical for its stability and function.

Under the microscope, the researchers observed several double helices intertwined with protein filaments.
