Answer
RNA stands for Ribonucleic Acid, a vital molecule essential for various biological processes within living organisms. Unlike Deoxyribonucleic Acid (DNA), which is double-stranded, RNA is a single-stranded molecule. It plays a crucial role in protein synthesis, acting as a messenger carrying genetic information from DNA to the ribosomes, where proteins are assembled. Messenger RNA (mRNA) is the most common form of RNA involved in this process.
