Which molecule regulates protein synthesis in animals?

The molecule that regulates protein synthesis in animals is ribonucleic acid (RNA). RNA plays a central role in the process of translating genetic information from DNA into proteins, which are essential for various biological functions.

During protein synthesis, messenger RNA (mRNA) is transcribed from DNA and carries the genetic code necessary for building proteins. This mRNA then interacts with ribosomes, which are the cellular structures where proteins are synthesized. Transfer RNA (tRNA) brings the appropriate amino acids to the ribosome in accordance with the sequence of the mRNA, ensuring that proteins are constructed correctly.

In summary, RNA is crucial for the regulation and execution of protein synthesis, as it serves both as the messenger conveying genetic information and as a facilitator that helps assemble amino acids into functional proteins.
