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.

AnswerThe "twisted ladder" shape of DNA is called a double helix.

Double Helix
Normally, DNA forms a right-handed double helix but it can also come in other forms.
The mitochondria and chloroplasts are used as evidence supporting the endosymbiotic theory. Both organelles have their own circular DNA, replicate independently of the cell, and have a double membrane structure similar to certain prokaryotes.
double helix
The coils of DNA are called double helix. This structure consists of two intertwined strands of nucleotides forming a twisted ladder shape.
The bases in DNA pair up in a specific way to form the double helix structure. Adenine pairs with thymine, and guanine pairs with cytosine. This pairing is called complementary base pairing, and it helps stabilize the double helix structure of DNA.
Yes, mitochondria have a double membrane structure.
