Hydrogen bonding
The double helical structure was discovered by Watson & Crick.
Yes, helical viruses have a rod-shaped structure. These viruses consist of a cylindrical or helical capsid that encloses the viral genetic material, which can be DNA or RNA. The helical capsid gives these viruses their rod-shaped appearance.
In an α-helix, the polypeptide backbone forms a repeating helical structure that is stabilized by hydrogen bonds between a carbonyl oxygen and an amine hydrogen. These hydrogen bonds occur at regular intervals of one hydrogen bond every fourth amino acid and cause the polypeptide backbone to form a helix.
By Spirochaetes, a helical bacteria which have a specialized internal structure known as the axial filament which is responsible for rotation of the cell in a spiral fashion and consequent locomotion, sort of like a corkscrew motion. Credit: MicrobiologyBytes, Bacterial Mobility
The helical nature was discovered by Rosalind Franklin and Watson and Crick first built the model of it.
The double helical structure was discovered by Watson & Crick.
"Helical" refers to its structure -- a helix (a spiral). See the related link below for an image.
helical structure of DNA
A helical virus has a spiraling structure similar to a spiral staircase. The virus genome is arranged in the middle of the spiral staircase. The Tobacco mosaic virus is a helical virus.
Helical piers are used to provide a foundation support for various types of structures. Helical piers are mostly used when there is a soil problem prohibiting a structure from failing.
Double helical structure
Protein is a chemical family name. Its shape may be helical. But a helical shape is of a spring type item shape.
It suggested that the structure of DNA was helical.
Yes, helical viruses have a rod-shaped structure. These viruses consist of a cylindrical or helical capsid that encloses the viral genetic material, which can be DNA or RNA. The helical capsid gives these viruses their rod-shaped appearance.
A helical structure is most efficient for storing huge amounts of genetic information in a small space
DNA is double helical (like a step ladder) in structure
In an α-helix, the polypeptide backbone forms a repeating helical structure that is stabilized by hydrogen bonds between a carbonyl oxygen and an amine hydrogen. These hydrogen bonds occur at regular intervals of one hydrogen bond every fourth amino acid and cause the polypeptide backbone to form a helix.
