Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The sugar-phosphate backbone of nucleic acid molecules is formed using which type of chemical bond?
A
Covalent
B
Ionic
C
Dipole-dipole
D
Hydrogen bonds
Explanation: 

Detailed explanation-1: -Therefore, the bond between sugar and phosphate is phosphoester bond which is a covalent bond.

Detailed explanation-2: -These bonds are called phosphodiester bonds, and the sugar-phosphate backbone is described as extending, or growing, in the 5’ to 3’ direction when the molecule is synthesized.

Detailed explanation-3: -The bond between the phosphate and hydroxyl group of sugar is an ester bond. DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds. Between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide.

Detailed explanation-4: -Phosphodiester bonds make up the backbones of DNA and RNA.

Detailed explanation-5: -Nucleotides are covalently linked to one another via the formation of phosphodiester bonds between the sugar group of one nucleotide and the phosphate group of a second nucleotide.
