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.

This alternates with phosphate to make up the sides of the DNA molecule?

Deoxyribose sugar alternates with phosphate to make up the sides of the DNA molecule. This forms the backbone of the DNA structure, with the phosphate group linking the sugar molecules together through phosphodiester bonds.

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 units make up The backbone of the DNA molecule?

The backbone of the DNA molecule is composed of alternating sugar (deoxyribose) and phosphate units. These sugar-phosphate units are connected by phosphodiester bonds to form the backbone of the DNA strand.

The rungs that are in the DNA ladder molecule are nucleotides. They are adenine, guanine, thymine and cytosine. Deoxyribose and phosphate make up the backbone of the molecule.


What two components make up the nucleotide backbone?

The two components that make up the nucleotide backbone are the sugar molecule, which is either ribose in RNA or deoxyribose in DNA, and the phosphate group. Together, they form the repeating structure that provides the backbone for the nucleic acid strand.
