Polynucleotides

Polynucleotides, often referred to as “PNs,” are a type of biopolymer composed of multiple nucleotide units linked together through phosphodiester bonds. Each nucleotide unit consists of a nitrogenous base (such as adenine, guanine, cytosine, or thymine in DNA; or adenine, guanine, cytosine, or uracil in RNA), a five-carbon sugar molecule (deoxyribose in DNA or ribose in RNA), and a phosphate group.

Polynucleotides play essential roles in biological processes, serving as the building blocks of nucleic acids such as DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). These molecules carry and store genetic information, encode instructions for protein synthesis, and regulate various cellular functions within living organisms. In summary, polynucleotides are fundamental biomolecules that play crucial roles in storing, transmitting, and expressing genetic information within living organisms. Understanding the structure and function of polynucleotides is essential for unraveling the complexities of genetics, molecular biology, and cellular processes in both health and disease.
