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.
What is the backbone of a DNA Molecule?
The DNA backbone is also called the sugar-phosphate backbone - the deoxyribose sugars (with, among other elements, 5 carbon atoms) and phosphates (PO4--) conjoin together in a [very strong due to the electronegativity of the Oxygens] chain.Sugars and PhosphatesA sugar (deoxyribose, a sugar with, among other elements, 5 carbon atoms) and phosphates to bond them together.
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 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 bonds hold RNA molecules together?
RNA molecules are held together by covalent bonds, such as phosphodiester bonds in the sugar-phosphate backbone. In addition, RNA molecules also form hydrogen bonds between complementary bases (A-U and G-C) in the double-stranded regions.
What bond type holds the sugar-phosphate backbone together?
phosphoester linkages
The bond that holds the DNA sugars together to form the backbone of DNA is?
Phosphate backbone
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 makes up the backbone of the DNA molecule?
The backbone of the DNA molecule is made up of alternating sugar (deoxyribose) and phosphate groups. These sugar-phosphate backbones run along the outside of the double helix structure, providing stability to the DNA molecule.
What are the two sides of the DNA and the helix held by?
The two sides of DNA are the sugar-phosphate backbone, which provides the structural support for the molecule. The helix is held together by hydrogen bonds between the nitrogenous bases on each side of the DNA molecule.
Two molecules forming sides of DNA ladder?
There are 4 nucleotides that make up the ladder: adenine and thymine, cytosine and guanine. There is a double bond between A and T, and a triple bond between C and G. The two substances that make up the SIDES of the ladder are sugar and phosphate, known as a sugar-phosphate strand.
What are the sides of a helix made of?
Each nucleotide has nitrogen sugar, a hydrogen bond, and on the sides a phosphate and a deoxyribose sugar
What type of bonds holds the sugar and phosphate groups together?
Phosphodiester bonds hold the sugar and phosphate groups together in DNA and RNA molecules. These bonds form between the phosphate group of one nucleotide and the 3'-hydroxyl group of the sugar in the adjacent nucleotide.
What binds the phosphate group to the next group?
In a nucleic acid, the phosphate group is bound to the next group (either another phosphate or a sugar) by a phosphodiester bond. This bond forms between the phosphate group's phosphate (-PO4) and the hydroxyl group (-OH) of the next group. The bond is formed through a dehydration reaction, where a water molecule is removed.
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.
What type of bond holds carbohydrates together?
glycosidic bonds
