What is the kind of covalent linkage which joins adjacent nucleosides in the same strand of DNA?
Adjacent nucleosides in DNA are joined by phosphodiester bonds, which are covalent bonds between the phosphate group of one nucleoside and the sugar group of another nucleoside. These bonds create the sugar-phosphate backbone of the DNA strand.
What types of bonds connect deoxyribose to the phosphate group?
Deoxyribose is connected to the phosphate group by phosphodiester bonds. These bonds form between the 3' hydroxyl group of the deoxyribose sugar and the phosphate group, linking adjacent nucleotides together in a DNA strand and creating the sugar-phosphate backbone essential for DNA structure.
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.
Will water be attracted or repelled by a phosphate group?
Water will be attracted to a phosphate group due to the presence of polar covalent bonds within the phosphate group. The oxygen atoms in the phosphate group will form hydrogen bonds with water molecules, leading to an attraction between the two molecules.
DNA is made up of bonded to a sugar phosphate backbone?
DNA is made up of nucleotides, which consist of a nitrogenous base (adenine, thymine, guanine, or cytosine), a sugar molecule (deoxyribose), and a phosphate group. These nucleotides are joined together by covalent bonds between the sugar of one nucleotide and the phosphate group of another, forming a sugar-phosphate backbone.
What is a group of joined by chemical bonds?
Molecule
What two parts make up the back bone of DNA?
The backbone of DNA is made up of repeating units of sugar (deoxyribose) and phosphate molecules. These molecules are connected by covalent bonds to form a sugar-phosphate backbone, with the nitrogenous bases extending from it.
How is the sugar phosphate backbone held together?
The sugar-phosphate backbone in DNA is held together by covalent bonds called phosphodiester bonds. These bonds link the 5' phosphate group of one nucleotide to the 3' hydroxyl group of the next nucleotide, forming a strong sugar-phosphate backbone that gives DNA its structural stability.
What type of bond is found between the phosphate groups?
In DNA, the phosphate groups are connected by phosphodiester bonds, which are covalent bonds formed between a phosphate group and two adjacent nucleotides in the DNA backbone.
What type of bond connects to the backbone of a DNA molecule?
The nucleotides are linked by peptide bonds - covalent bonds between the carbon in the carboxyl group and the nitrogen in the amino group. The double helix is formed by hydrogen bonds between the hydrogens and oxygens of two strands of nucleotides.
The energy of the Atp molecule is stored within which phosphate groups?
The energy of the ATP molecule is mainly stored in the high-energy bonds of the outermost phosphate group, known as the gamma phosphate group. When this phosphate group is hydrolyzed, releasing energy, it forms ADP (adenosine diphosphate) and inorganic phosphate.
What is the energy When the outer phosphate group detaches from ATP?
It is an unstable bond.30.7Kj per mole of ATP is produced.
