1. Messenger RNA (mRNA): This molecule carries the genetic code from the DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis takes place. It contains the sequence of codons that specify the order of amino acids in the protein.
2. Transfer RNA (tRNA): This molecule acts as an adaptor between the mRNA codons and the amino acids. Each tRNA molecule carries a specific amino acid and recognizes a specific codon on the mRNA through its anticodon loop.
3. Ribosomes: These are complex molecular machines composed of ribosomal RNA (rRNA) and proteins. They provide the framework for translation and catalyze the formation of peptide bonds between amino acids.
