What make up the backbone of a polynucleotide strand?
The backbone of a polynucleotide strand is composed of alternating sugar (deoxyribose or ribose) and phosphate molecules. The sugar-phosphate backbone provides the structural support for the nucleotide bases, which extend from the backbone and form interactions with bases on the opposite strand in DNA or RNA molecules.
What constitutes the backbone of DNA?
The backbone of DNA is made up of sugar molecules and phosphate groups. These molecules form a repeating pattern along the length of the DNA strand, providing structural support and stability to the molecule. The nitrogenous bases are attached to this backbone, forming the genetic code of DNA.
What type of chemical bond holds together the backbone of a strand of DNA?
Covalent bonds between a sugar molecule (deoxyribose) and a phosphate group make up the backbone of DNA. These are very strong covalent bonds and are broken only with great expenditure of energy--x-rays, for example.
What parts of the nucleotide make up the backbone of the DNA molecule?
Pentose sugars and Phosphate groups
The two molecules that alternate to form the backbone of a polynucleotide chain are?
The two molecules that alternate to form the backbone of a polynucleotide chain are deoxyribose sugar and phosphate groups, which create a sugar-phosphate backbone. These molecules bond together through phosphodiester bonds to form the structure of DNA and RNA.
In DNA what do phosphate groups bond to?
Phosphate groups in DNA bond to sugar molecules through a phosphodiester bond to form the backbone of the DNA strand.

What sugar molecules is involved in the structure of DNA?
Deoxyribose sugar molecules are involved in the structure of DNA. These sugar molecules are part of the backbone of the DNA double helix, linking with phosphate groups to form the sugar-phosphate backbone of the DNA strand.
What type of chemical bond holds together the backbone of a strand of DNA?
Covalent bonds between a sugar molecule (deoxyribose) and a phosphate group make up the backbone of DNA. These are very strong covalent bonds and are broken only with great expenditure of energy--x-rays, for example.
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.
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.
Many time the molecule join to form long chains with what kind of backbone?
Molecules often join to form long chains with a carbon backbone, which is fundamental in organic chemistry. This carbon backbone allows for various functional groups to be attached, leading to diverse chemical properties and structures. In addition to carbon, other elements like silicon can also serve as backbones in specific types of compounds. These long chains can form polymers, proteins, and other complex molecules essential for life.
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 makes up the outside of the dna ladder?
The outside of the DNA ladder is made up of a sugar-phosphate backbone. The sugar in DNA is deoxyribose, which alternates with phosphate groups to form the backbone. The nitrogenous bases are attached to this sugar-phosphate backbone on the inside of the ladder.
What are The bones that form the backbone are called?
Vertebrae are the bones that form the backbone.
Name two molecules which alternate to make the upright or side portion of a DNA molecule?
The two molecules that alternate to form the backbone of a DNA molecule are deoxyribose sugar and phosphate groups. These molecules form a repeating pattern along the length of the DNA strand, with the nitrogenous bases (adenine, thymine, cytosine, and guanine) attached to the deoxyribose sugar molecules.
