Answer:
The steps in translation are:
- <em>The ribosome binds to mRNA at a specific area.
</em>
- <em>The ribosome starts matching tRNA anticodon sequences to the mRNA codon sequence.
</em>
- <em>Each time a new tRNA comes into the ribosome, the amino acid that it was carrying gets added to the elongating polypeptide chain.
</em>
- <em>The ribosome continues until it hits a stop sequence, then it releases the polypeptide and the mRNA.
</em>
- <em>The polypeptide forms into its native shape and starts acting as a functional protein in the cell.</em>
