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.


How does RNA form a double helix structure?

RNA does not typically form a double helix structure like DNA. Instead, RNA molecules usually exist as single strands that can fold into complex shapes due to their sequence and interactions with other molecules.


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.


Can RNA form a double helix structure?

No, RNA cannot form a double helix structure like DNA.


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.


What is the connecting element between the pairs of strands that form the double helix of DNA?

The connecting element between the pairs of strands that form the double helix of DNA is hydrogen bonds.


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.
