Translation takes place on ribsomes, which can be found on the rough endoplasmic reticulum (ER) or within the cytoplasm. 

Once the mRNA has been exported from the nucleus it binds to a ribsome. The ribosome scans along the mRNA reading each codon, after reading the codon, the ribosome facilitates the correct tRNA to bring in the correct specific amino acid that is required. Anti codons and codons match up by forming correct complementary base pairs. This pairing allows a peptide bond to form and adjacent amino acids join together. This process continues along the mRNA which will create a polypeptide. Once a stop codon is reached, the mRNA falls off the ribsome and the polypeptode is finished.
