Do proteins contain a sugar-phosphate backbone?

The sugar-phosphate backbone has a negative charge that allows DNA to easily dissolve in water and is also used by proteins that bind the DNA. These proteins often have positive areas that bind strongly to the negative charge of the phosphate groups.

What is a sugar backbone?

The sugar phosphate backbone is an important stuctural component of DNA. It consists of 5-carbon deoxyribose sugars and phosphate groups. These sugars are linked together by a phosphodiester bond, between carbon 4 of their chain, and a CH₂ group that is attached to a phosphate ion.

What is the sugar backbone made of?

A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

What macromolecule has a sugar-phosphate backbone?

Ribonucleic acid (RNA) is a long macromolecule built from nucleotides strung together along a sugar-phosphate backbone.

What is made up of sugar phosphate and base?

A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.

What bonds hold the sugar phosphate backbone together?

The bond formed between the sugar of one nucleotide and the phosphate of an adjacent nucleotide is a covalent bond. A covalent bond is the sharing of electrons between atoms. A covalent bond is stronger than a hydrogen bond (hydrogen bonds hold pairs of nucleotides together on opposite strands in DNA).

What is the sugar backbone of DNA?

Explanation: DNA stands for "deoxyribonucleic acid." The backbone of DNA is comprised of alternating sugar and phosphate units, in which the sugar is deoxyribose. The backbone of RNA is also comprised of sugar and phosphate units, but uses the sugar ribose.

What type of sugar is used for the backbone of RNA?

ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds to nitrogenous bases.

What is the sugar-phosphate backbone and why is it described that way ?'?

Sugar-phosphate backbone is composed of alternating sugar and phosphate that defines directionality of the molecules which is negatively charged and hydrophilic to allow the DNA backbone to form bonds with water. ...

What are the three parts of a nucleotide which parts make up the backbone of a DNA strand?

The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 9.3).

Is the backbone of DNA hydrophobic?

The negative charge of the backbone, along with the OH-groups on the deoxyribose sugar, means that the backbone is Hydrophillic as water can form hydrogen bonds with it. The centre of the DNA molecule is hydrophobic due to the lack of charge in DNA bases.

What makes up the DNA backbone?

​Phosphate Backbone

DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T).

Why is the sugar-phosphate backbone on the outside?

The sugar-phosphate backbone is on the outside of the helix where the polar phosphate groups (red and yellow atoms) can interact with the polar environment. The nitrogen (blue atoms) containing bases are inside, stacking perpendicular to the helix axis.

What macromolecule contains sugar-phosphate and nitrogenous base?

Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base.

Which sugar residue is present in the sugar-phosphate backbone of RNA?

The sugar in the sugar-phosphate backbone of RNA is ribose, not deoxyribose as in DNA.
