Helix goderdziana was created in 2008.
A collagen helix is less compact (because it goes into triple helices), and it is a left-handed helix. An alpha helix is more compact and hence requires more rotation of bonds to form (hence proline is not very common...has an imidazole ring). It is a right-handed helix, and goes into double helices instead.
The main difference between a right-handed alpha helix and a left-handed alpha helix in protein structures is the direction in which the helix twists. In a right-handed alpha helix, the helix twists in a clockwise direction, while in a left-handed alpha helix, the helix twists in a counterclockwise direction. This difference in twisting direction affects the overall shape and stability of the protein structure.
The double helix of DNA is more stable than a single helix due to the hydrogen bonding between complementary base pairs and the structural support provided by the sugar-phosphate backbone. The double helix structure allows for efficient storage and replication of genetic information.
Its actually two wi=ords; Thehy are 'Double Helix'.
Watson and Crick's DNA model is a double helix structure, where two strands of DNA wind around each other. They proposed this model in 1953, based on X-ray crystallography data collected by Rosalind Franklin and Maurice Wilkins. Their model explained how genetic information is stored and replicated in the DNA molecule.
