The sides of the DNA double helix are formed by alternating sugar (deoxyribose) and phosphate molecules, which make up the backbone of the structure. The sugar-phosphate backbone provides stability and support for the nitrogenous bases in the center of the helix.

What is a double helix DNA or RNA?
A double helix is a twisted ladder-like structure that describes the shape of DNA. DNA is a molecule that carries genetic information in organisms. RNA is another type of nucleic acid that can form double helix structures under certain conditions, but it is less stable in this form compared to DNA.
What causes the two sides of a double helix of DNA to stay joined together?
The two sides of a double helix of DNA are held together by hydrogen bonds between complementary base pairs (adenine with thymine, and guanine with cytosine). These bonds form a stable structure that allows DNA to maintain its shape and function properly.
DNA molecules has how many strands?
DNA molecules have two strands that are twisted together to form a double helix structure. Each strand is made up of a sequence of nucleotides containing genetic information.
What are the two parts of the DNA that make up the sides of the double helix?
The two parts of DNA that make up the sides of the double helix are sugar molecules (deoxyribose) and phosphate groups. These molecules alternate to form the sugar-phosphate backbone of the DNA molecule.
What is the shape of a DNA molecule formed when two twisted DNA strands are coiled into a springlike structure?
The shape of a DNA molecule formed when two twisted DNA strands are coiled into a springlike structure is a double helix. This structure resembles a twisted ladder, with the sugar-phosphate backbone forming the sides of the ladder and the paired nitrogenous bases forming the ladder's rungs.
What structures form the rungs of the DNA double helix?
The rungs of the DNA double helix are made up of alternating deoxyribose sugar molecules and phosphate molecules. Please refer to the related link below.
What 2 molecules make up the sides of the DNA molecule?
The two molecules that make up the sides of the DNA molecule are deoxyribose sugar and phosphate groups. These molecules alternate to form the sugar-phosphate backbone of the DNA double helix structure.
How many sugar phosphate backbones does a double helix have?
A double helix structure has two sugar-phosphate backbones, one on each side of the helix. These backbones are made up of alternating sugar and phosphate molecules that support the DNA bases in the helix.
What is a double helix DNA or RNA?
A double helix is a twisted ladder-like structure that describes the shape of DNA. DNA is a molecule that carries genetic information in organisms. RNA is another type of nucleic acid that can form double helix structures under certain conditions, but it is less stable in this form compared to DNA.
What molecles form the sides of the ladder?
I'm assuming you mean the double helix "ladder-like" formation of a strand of DNA. The sides of the structure are essentially a phosphate-deoxyribose backbone.
What is the form of DNA called?
a double helix
How are DNA molecules bound together to form a double helix?
The DNA strands are held together by hydrogen bonds between complimentary base pairs.
What are Molecules of DNA are referred to as?
The molecules of DNA are referred to as nucleotides, which are the building blocks of DNA. Nucleotides consist of a sugar (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). Multiple nucleotides are strung together to form the double helix structure of DNA.
Who was responsible for the discovery of DNA as a double helix?
Scientists by the name of James Watson and Francis Crick discovered DNA to be in the form of a double helix.
What shape do two strands of DNA form?
double helix
When DNA is in its thread like form what is it referred as?
Double Helix
What structure in the nucleus holds the DNA?
The DNA molecule forms a double helix. The linear DNA chromosomes of eukaryotes form a highly supercoiled double helix.
