Question

What is the phosphodiester bond and how it is drawn?

Answer 1

Hint:To solve this question, first we have to understand the term phosphodiester bond. To draw a phosphodiester bond, we should have prior knowledge about the connectivity which leads to the formation of the bond.

Complete answer:
Phosphodiester bond is universal to all the life forms which are present on the earth because the phosphodiester bond is present in the backbone of both DNA and RNA. DNA stands for deoxy ribonucleic acid and RNA stands for ribonucleic acid. The DNA consists of two polynucleotide chains which are connected by the strong electromagnetic attraction also known as the phosphodiester bond.
The Phosphodiester bond is a covalent bond which is generally formed between the phosphate group of ${{5}^{'}}$ carbon of one of the nucleotides and ${{3}^{'}}$ carbon of another nucleotide through the formation of ester linkage. This bond is formed due to the condensation reaction occurring between the hydroxyl group of two sugar groups and the one phosphate group and a bond which is responsible for the linkage of ${{5}^{'}}$ carbon of one of the nucleotides and ${{3}^{'}}$ carbon of another nucleotide through the formation of ester linkage in DNA and RNA.
Phosphodiester linkage is shown below:

Note:
The formation of Phosphodiester bonds is a synthetic process or also known as building up process. Thus, it is an anabolic process. An anabolic process is the process in which energy is used along with the elimination of the water molecule. The bond formed in the Phosphodiester bond is a covalent bond.
