What is a phosphodiester bond​

The correct answer is - A covalent bond between a phosphate group and two 5-carbon ring carbohydrates over two ester bonds.

Explanation:

A bond between a 5 carbon sugar and a phosphate group makes the sugar-phosphate-sugar backbone in nucleic acids. A diester bond links two different nucleotides together to form a polynucleotide.

These are the strong covalent bonds that links a 3' carbon atom of one sugar molecule and the 5' carbon atom of another in deoxyribose sugar in DNA and ribose sugar in RNA.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
