double helix, twisted ladder, spiral staircase.
It is known or referred to as a "double helix" because it is made up of two strands(made up of molecular bases and sugar) that intertwines in a spiral manner
A double helix

The first picture and model of the DNA structures were made from Rosalind Elsie Franklin. Over the years William Watson and Francis Crick stole the idea from her and worked out the structure of DNA as if they invented it.

Double Helix
A DNA structure is basically what genes are meant to be the dna model stands for deoxribosenuleic acid
The double helix model became the accepted structure of DNA because it fit the experimental evidence, especially from X-ray crystallography of the DNA molecule.
The discovery of the structure of DNA was a culmative effort. After the discovery that the genes were paired, Watson and Crick suggested the first accurate model of DNA structure in the journal of Nature.

Double helical structure
AnswerThe "twisted ladder" shape of DNA is called a double helix.
The sugar-phosphate supporting structure of the DNA double helix is called the backbone. This is why the DNA is commonly referred to as a double helix.
The supporting structure of the DNA double helix is called the sugar-phosphate backbone.
Dna for the building of protein on a cytoplasmic structure called ribosomes. RNA leaves the nucleus and carries out the instructions.
