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.
