Describe the process of translation in protein synthesis

-  Following transcription, the mRNA (messenger RNA) leaves the nucleus via the nuclear pores and enters the cytoplasm. It then attaches to a ribosome

- tRNA molecules in the cytoplasm carry a single amino acid. They also have 3 base pairs of RNA molecules that correspond to that amino acid. This is called the anticodon.

- A tRNA molecule with a complementary anticodon to the first codon (the start codon) of the mRNA molecule binds to the mRNA molecule. This is complementary base pairing.

- Hydrogen bonds form between the mRNA and tRNA molecules. 

- A second tRNA molecule binds to the adjacent codon on the mRNA molecule. This allows a peptide bond to form between the protiens on the tRNA molecules.

- The peptide bond is formed by a condensation reaction. 

The first tRNA molecule leaves the ribosome

- The ribosome moves along the mRNA and the process repeats. The length of the polypeptide chain increases and translation stops when the ribosome reaches the stop codon on mRNA.
