What are the three major types of RNA molecules? How is each related to the concept of information flow?

Answer: The three major types of RNA molecules are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). They are related to the concept of information flow in the following ways: 1. mRNA carries the genetic code from DNA in the nucleus to the ribosomes, where it serves as a template for protein synthesis, transferring genetic information to facilitate the assembly of proteins. 2. tRNA decodes the genetic sequence in mRNA by pairing its anticodon with the corresponding mRNA codon, ensuring the correct amino acids are brought to the growing polypeptide chain during protein synthesis. 3. rRNA provides the structural framework and catalytic activity required for the translation of mRNA into proteins, enabling the proper functioning of the ribosome during protein synthesis.
