Functions of Nucleic Acids: Genetic Information Storage, Protein Synthesis, Regulation

Introduction to Nucleic Acids: Definition and Importance in Biology

Nucleic acids, primarily consisting of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), play a fundamental role in the biological framework of all living organisms. Their primary function is to store, transmit, and express genetic information. Without nucleic acids, the processes that underpin life—including growth, reproduction, and adaptation—would not be possible.

Types of Nucleic Acids: DNA vs RNA

Introduction to Nucleic Acids: Definition and Importance

Nucleic acids, namely DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are fundamental macromolecules that play crucial roles in the biochemistry of life. Defined as long chains of nucleotides, these molecules are responsible for storing, transmitting, and expressing genetic information in all living organisms. Their discovery and subsequent research have been pivotal, influencing fields such as genetics, molecular biology, and biotechnology.
