Here are the essential concepts you must grasp in order to answer the question correctly.
Nucleic Acids
Nucleic acids, such as DNA and RNA, are biopolymers essential for all forms of life. They are composed of long chains of nucleotides, which are the basic building blocks. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. Understanding nucleic acids is crucial for grasping how genetic information is stored and transmitted.

Phosphodiester Linkage
A phosphodiester linkage is a chemical bond that connects the 5' phosphate group of one nucleotide to the 3' hydroxyl group of another nucleotide. This bond forms the backbone of nucleic acid strands, providing structural integrity and directionality. The formation of these linkages is vital for the stability and function of polynucleotides.

Polynucleotide Structure
Polynucleotides are long chains of nucleotides linked together by phosphodiester bonds. They can be single-stranded, as in RNA, or double-stranded, as in DNA. The sequence of nitrogenous bases along the polynucleotide chain encodes genetic information, making the understanding of their structure essential for molecular biology and genetics.
