what is the cooperative function of RNA molecules (mRNA,tRNA and rRNA)?

mRNA, tRNA, and rRNA function together in protein synthesis.

mRNA (messenger RNA) carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm. It provides a template for protein synthesis, and specifies the sequence of amino acids that make up the polypeptide chain.

tRNA (transfer RNA) is responsible for bringing each amino acid to the ribosome during protein synthesis. Its role is to match the amino acid to the correct codon on the mRNA, ensuring that the correct sequence of amino acids is assembled to form the protein.

rRNA (ribosomal RNA) is a major component of ribosomes, the organelles that synthesize proteins. It provides a framework for the ribosome and catalyzes the formation of peptide bonds between amino acids during protein synthesis.

Therefore, mRNA, tRNA, and rRNA function together to ensure accurate and efficient protein synthesis.
