The structure of DNA features a sugar-phosphate backbone composed of alternating deoxyribose sugar and phosphate groups. This backbone provides structural stability and supports the attachment of nitrogenous bases, which pair to form the rungs of the DNA double helix. The sequence of these bases encodes genetic information. Overall, the sugar-phosphate backbone is essential for maintaining the integrity and function of the DNA molecule.
What else can I help you with?
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.
Do RNA molecules have a sugar phosphate backbone?
Yes, RNA molecules have a sugar-phosphate backbone. This backbone is composed of alternating sugar (ribose) and phosphate groups, which provide structural stability and support for the RNA strand. The ribose sugar in RNA distinguishes it from DNA, which contains deoxyribose. Additionally, the sequence of nitrogenous bases attached to the sugar backbone encodes genetic information.
What is the sequence of subunits in the DNA backbone?
The DNA backbone consists of alternating sugar (deoxyribose) and phosphate groups. The sugar-phosphate backbone is formed by the covalent bonds between the sugar of one nucleotide and the phosphate group of the next nucleotide. This forms a repeating pattern of sugar-phosphate-sugar-phosphate along the DNA strand.
If the structure of DNA were likened to a ladder what would make up the supporting structure (not the rungs) of a ladder?
If the structure of DNA is likened to a ladder, the supporting structure would be the sugar-phosphate backbone. This backbone consists of alternating sugar (deoxyribose) and phosphate groups that provide structural support to the DNA molecule, holding the rungs (the nitrogenous base pairs) together. Just like the sides of a ladder, the sugar-phosphate backbone maintains the integrity and stability of the DNA double helix.
Which marcomolecules contains sugar ribose?
Ribose is a sugar molecule found in RNA (ribonucleic acid), one of the main types of nucleic acids in cells. It is a key component of the ribose-phosphate backbone that forms the structure of RNA molecules.
Does RNA contain a phosphate group like DNA?
Yes, RNA contains a phosphate group in its backbone, just like DNA. The phosphate group is important for forming the sugar-phosphate backbone that gives RNA its structure and stability.
What is the sugar phosphate supporting structure of the DNA double helix called?
The sugar-phosphate supporting structure of the DNA double helix is called the backbone. This is why the DNA is commonly referred to as a double helix.
What is the relationship between a phosphate base and sugar in the structure of DNA?
In the structure of DNA, a phosphate base is connected to a sugar molecule through a covalent bond. This bond forms the backbone of the DNA molecule, with the phosphate-sugar backbone providing stability and structure to the double helix shape of DNA.
What constitue the backbone structure of nucleic acid chains?
phosphate and sugar
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.
Does nucleic acid have sugar phosphate backbone?
Yes, nucleic acids have a sugar-phosphate backbone. The backbone is formed by a repeating pattern of sugar molecules (deoxyribose in DNA, ribose in RNA) connected to phosphate groups. The nitrogenous bases are attached to this backbone to form the overall structure of DNA and RNA.
Do RNA molecules have a sugar phosphate backbone?
Yes, RNA molecules have a sugar-phosphate backbone. This backbone is composed of alternating sugar (ribose) and phosphate groups, which provide structural stability and support for the RNA strand. The ribose sugar in RNA distinguishes it from DNA, which contains deoxyribose. Additionally, the sequence of nitrogenous bases attached to the sugar backbone encodes genetic information.

The DNA backbone consists of alternating sugar (deoxyribose) and phosphate groups. The sugar-phosphate backbone is formed by the covalent bonds between the sugar of one nucleotide and the phosphate group of the next nucleotide. This forms a repeating pattern of sugar-phosphate-sugar-phosphate along the DNA strand.
Does Deoxyribose bond to phosphate in DNA?
Yes, deoxyribose sugar molecules in DNA form covalent bonds with phosphate groups to create the sugar-phosphate backbone of the DNA molecule. This alternating sugar-phosphate backbone provides stability and support to the DNA double helix structure.
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 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.
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.
