1. PROTEIN SYNTHESIS
The Central Dogma = really important idea

2. Central Dogma
• DNA  RNA Protein
• Controlling the proteins in an organism controls
the organism’s characteristics.

3. Central Dogma

4. Step 1: Transcription
• In eukaryotes it occurs in the nucleus.

5. Steps:
• 1) RNA polymerase (enzyme)
• Binds to DNA and separates the two
strands.

6. • 2) One strand of DNA is used as the
template to make messenger RNA.
• RNA nucleotides are added to growing
strand.
• No thymine in RNA has uracil instead
• A=U and G=C

7. DNA strand = ATCGTGCA
What would be the mRNA strand created?

8. • 3) Single stranded mRNA created and
process is called transcription.
• mRNA leaves the nucleus to go to the
ribosomes where it’s code is used to create
a protein.
