In the ladder like model of DNA the sides upright consists?

The upright sides of the ladder-like model of DNA consist of alternating sugar (deoxyribose) and phosphate molecules, which make up the backbone of the DNA molecule. The sugar-phosphate backbone provides structural support and stability to the DNA molecule.


What molecules make up the the sides of a DNA molecule?

The sides of a DNA molecule are made up of alternating deoxyribose sugar and phosphate molecules, linked together by phosphodiester bonds. This forms the backbone of the DNA double helix, with the nitrogenous bases projecting inward towards each other.


What 2 substances make up the backbone or the sides of the DNA molecule?

The sugar-phosphate backbone of DNA is made up of deoxyribose (a sugar) and phosphate.


What Sugar used in DNA to make up the backbone?

Deoxyribose sugar, it is a pentose sugar base.


What are the sides of the DNA ladder composed of?

The sides of the DNA ladder is composed of sugar and phosphate. 4 bases that make up the rungs of the DNA ladder are A, T, G, and C. The shape of the DNA is a double helix or twisted ladder.


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.


What substances make up the side of the DNA ladder?

The sides of the DNA ladder are made up of alternating sugar (deoxyribose) and phosphate molecules. These sugar-phosphate backbones run along the outside edges of the DNA molecule, providing structural stability.


What are the two parts of the DNA that make up the sides of the double helix?

I'm not sure I understand your question, but DNA is a huge molecule formed by two very long polynucleotide strands. They are linked together by hydrogen bonds between complimentary pairs of nitrogen bases. It looks something like a ladder. Sugar-phosphate would be like the rails of the ladder and the paired nitrogen bases would be like the steps. Hope this helps somewhat.


What Make up the side of the DNA molecule?

A phosphate group bonded covalently to a sugar molecule.


What are the molecules that make up the sides of DNA?

The two sides of DNA latter are made up of molecules of a sugar called deoxyribose alternating with molecules known as phosphates PHOSPHATES AND SUGAR


What are sides of a double helix made of?

The sides of a double helix are made of repeating units of sugar and phosphate molecules, which make up the backbone of the DNA molecule. These sugar-phosphate backbones are connected by hydrogen bonds between the nitrogenous bases, forming the characteristic twisting structure of the DNA double helix.
