1. Messenger RNA (mRNA): This type of RNA carries the genetic code from DNA in the nucleus to the ribosomes in the cytoplasm. It acts as a blueprint for protein synthesis.

2. Transfer RNA (tRNA): These molecules transport amino acids to the ribosomes, where they are added to the growing polypeptide chain based on the instructions in the mRNA.

3. Ribosomal RNA (rRNA): This type of RNA is a major component of ribosomes, the cellular machinery that reads the mRNA and assembles the protein. rRNA plays a crucial role in the proper functioning of ribosomes, ensuring accurate protein synthesis.
