Translation
- The anticodons on the tRNA match up with codons on the mRNA.
- The ribosome moves along the mRNA and another tRNA molecule enters. A condensation reaction forms a peptide bond between the two amino acids.
- The tRNA molecules with complementary anticodons enter the ribosome, each carrying a specific amino acid.
- Two tRNA molecules are in the ribosome at the same time, attached to two codons, as the peptide bond formation is catalysed.
- The mRNA attaches to a ribosome at a start codon.
- The ribosome continues to move down the mRNA, releasing the previous tRNA molecule and repeating the process. This occurs until a stop codon is reached and the ribosome detatches.
- The mRNA moves out of the nucleus through a nuclear pore and into the cytoplasm.
