covalent bond
|
|
|
phosphodiester bonds
|
|
|
nucleotide bonds

|
all of the above
|
Explanation:
Detailed explanation-1: -The bond formed in the Phosphodiester bond is a covalent bond.
Detailed explanation-2: -The correct option is C. 3’-5’ Phosphodiester bond. A phosphodiester bond is a linkage in which 3’ phosphate group of a nucleoside is linked to the 5’ hydroxyl group of another nucleoside. The direction is always from the 3’ to 5’ in nucleotides.
Detailed explanation-3: -Phosphodiester bonds are covalent in nature and thus are formed by the sharing of electrons between their atoms. Moreover, the enzymes that usually break the phosphodiester bonds are called phosphodiesterase abbreviated as PDE.
Detailed explanation-4: -1 Answer. Nucleotides are joined by phosphodiester bonds in a polynucleotide strand.
