37. Verbal Summary
• Protein synthesis begins in the nucleus with DNA and is called
Transcription. The DNA is untwined by RNA polymerase and then a
mRNA strand is created. The mRNA travels outside the cell into the
cytoplasm and onto the second step of protein synthesis called
translation. The mRNA stand goes to a ribosome and bonds with it.
Then tRNA comes with an anti codon and an amino acid and goes
through the chain of mRNA. Then at the end of the chain a stop
codon comes without an amino acid and ends the chain of amino
acids that are chained together by peptide bonds. The amino acids
then form together into a tertiary structure.
