Protein Synthesis

- synthesizing mRNA, directed by DNA

- synthesizing polypeptide chain,directed by RNA

- DNA

- mRNA

- Nucleotides of RNA

- mRNA

- tRNA

- Ribosomes

- Amino Acids

- Translation

- Transcription

- 1) DNA begins to uncoil

- 2) One strand begins synthesis

- 3) mRNA is synthesized

- 4) Both DNA strands recouple

- 5) Processed mRNA leavesnucleus, enters cytoplasm

- 1) tRNA carries amino acids to mRNA

- 2) tRNA anticodon pairs with mRNA codon

- 3) Ribosomes move down mRNA chain

- 4) First tRNA detaches frommRNA, allowing it to advanceforward

- 5) When "STOP" codon is reached, process endsand an animo acid chain is released from theribosome

- 6) Amino acid chains become proteins

- To create new copies of mRNA

- To create new amino acidchains, forming new proteins
