Ester linkages occur in:
Correct answer: A. Nucleic acids
- A. Nucleic acids
- B. Nucleus
- C. Carbohydrates
- D. Proteins
Explanation
DNA and RNA are the chain of polynucleotides, that are joined by ester linkage known as 'phosphodiester bonds'. The two nucleotides, within a nucleotide chain, are linked by a phosphodiester bond. It is formed by the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another, with the phosphate group acting as a bridge between the 2 carbons.So, the correct answer is option A.

About Classification of Biological Molecules
Biological molecules are classified as carbohydrates, lipids, proteins and nucleic acids, with water, minerals and vitamins also supporting cellular processes. The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
