DNA and the Language of Life (chapter 11 of

the book)

• Steps from Gene to Protein1.TRANSCRIPTION: 2 MAIN phases Transcription: Copying DNA to m RNA (pre

m RNA)

Editing: RNA Splicing

(All inside the nucleus)

3

Steps from Gene to ProteinTranscription: DNA to RNA Template strand of DNA Newly made m RNA* RNA polymerase

*Pre m RNA

4

Steps from Gene to ProteinTranscription: DNA to pre mRNA

3 steps: Initiation Elongation Termination

5

RNA splicing

• Intron: non coding sequence

• Exon: coding sequence

Steps from Gene to Protein

Introns stay IN nucleus

Exons EXit nucleus

Final mRNA doesn’tContain introns

Form pre m RNA to m RNA

6

RNA splicing• Intron: non coding

sequence• Exon: coding sequence

7

Steps from Gene to Protein

Translation: m RNA to Protein

3 steps: Initiation Elongation Termination

8

Steps from Gene to Protein

Translation: RNA to Protein

1.Initation: Translation begins with the attachment of a ribosome and the first tRNA to a "start" (AUG) codon.

9

Steps from Gene to ProteinTranslation: RNA to Protein

2.Elongation The ribosome moves along the mRNA. The polypeptide elongates as an amino acid is added for each codon.

10

Steps from Gene to Protein

Translation: RNA to Protein

3. Termination:When the ribosome arrives at a "stop" codon, the completed polypeptide is released
