RNA, or Ribonucleic Acid, is one of the fundamental building blocks of life, playing a pivotal role in genetic coding, decoding, and regulation. Distinct from DNA, RNA is a single-stranded molecule that acts as an intermediary in protein synthesis and cellular regulation. This blog dives into the diverse roles and techniques associated with RNA, drawing from a comprehensive review of its mechanisms and innovations.
Key Differences Between RNA and DNA
RNA is often referred to as the more "dynamic" counterpart of DNA. While DNA stores genetic information in a double-helical structure, RNA is single-stranded and designed for active cellular processes. Key distinctions include:
- RNA contains uracil instead of thymine.
- Its single-strand configuration allows for rapid transcription and translation processes.
