Final answer:
mRNA carries genetic information, tRNA brings amino acids, rRNA forms ribosomes.
Step-by-step explanation:
The three major types of RNA molecules involved in protein synthesis are:
- mRNA (messenger RNA): carries the genetic information from DNA to the ribosomes in the cytoplasm. It serves as a template for protein synthesis by providing the sequence of codons.
- tRNA (transfer RNA): brings the amino acids to the ribosomes during protein synthesis. Each tRNA molecule has an anticodon that complements the codon on the mRNA, ensuring the correct association of amino acids.
- rRNA (ribosomal RNA): combines with proteins to form ribosomes, which are the site of protein synthesis. It also has enzymatic activity and catalyzes the formation of peptide bonds between amino acids.
