DID YOU KNOW

– RNA, or ribonucleic acid, is a molecule that plays a crucial role in the transfer of genetic information from DNA to proteins. It is found in all living organisms and is essential for various biological processes.

– Did you know that RNA can have different forms and functions? One type of RNA, called messenger RNA (mRNA), carries the genetic instructions from DNA to the ribosomes, where proteins are synthesized. Another type, transfer RNA (tRNA), helps in translating the genetic code into proteins by bringing the amino acids to the ribosomes.

– RNA molecules can also have catalytic activity, meaning they can act as enzymes. These RNA enzymes, known as ribozymes, can perform various chemical reactions, including cutting and joining RNA strands. This discovery challenged the long-held belief that only proteins could act as enzymes and opened up new possibilities for understanding the origins of life and developing RNA-based therapies.
