What is it?
Nucleic acids are large, essential biomolecules found in all living things, from viruses to humans. They are polymers made of repeating units called nucleotides. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is a double helix structure that carries the genetic blueprint for an organism's development, functioning, and reproduction. RNA is typically single-stranded and plays a crucial role in translating the genetic information from DNA into proteins.
Why is it trending?
The study of nucleic acids is at the forefront of biological and medical innovation. Advances in DNA sequencing technology have revolutionized personalized medicine, forensics, and our understanding of evolution. Furthermore, RNA technology has gained significant attention with the rapid development of mRNA vaccines, which instruct human cells to build specific proteins to trigger an immune response. This has opened new avenues for treating a wide range of diseases beyond infectious ones, including cancer and genetic disorders, making nucleic acid research a constantly evolving and high-impact field.
How does it affect people?
Nucleic acids are fundamental to human existence. DNA determines our inherited traits, such as eye color and predisposition to certain diseases. It holds the instructions for building and maintaining our bodies. RNA is essential for protein synthesis, the process that creates the enzymes and structural components necessary for virtually every bodily function. Errors in our nucleic acid sequences can lead to genetic disorders. Understanding nucleic acids is therefore critical for diagnosing, treating, and potentially curing a vast number of human diseases, impacting health and medicine on a profound level.
