RNA (Royal National Association)

RNA, or Ribonucleic Acid, is a molecule that plays a vital role in cellular processes, particularly in synthesizing proteins. It acts as a messenger, carrying instructions from DNA in the nucleus to other parts of the cell where proteins are made. RNA is similar to DNA but is usually single-stranded and contains a different sugar molecule. Its functions include translating genetic information into functional proteins and regulating gene activity. Essentially, RNA is essential for turning the genetic code into the physical traits and functions of living organisms, making it a key component of biological systems.
