DNA Translation

Step 1 The mRNA attaches itself to a ribosome,
and the first codon is translated.

Step 2 A second tRNA molecule bonds with the
next 3 exposed bases. This one brings a different
amino acid.

Step 3 The ribosome now moves along the mRNA
exposing the next three bases on the ribosome.
A third tRNA molecule brings a third amino acid,
which joins to the second one. The first tRNA
leaves.

The polypeptide chain continues to grow, until a
stop codon is exposed on the ribosome,
translation ceases and the polypeptide is
finished.
