STEPS OF PROTEIN SYNTHESIS
HOW DOES MRNA TELL THE CELL WHAT TO
DO?
mRNA is a message that codes for a protein
 Proteins are made in the cytoplasm and then work
to keep the cell alive
 Translation (protein synthesis): Process of making
a protein
 Proteins are made up of amino acids (small
building blocks)
 There are 20 different types of amino acids

PROCESS OF TRANSLATION
1.
mRNA moves out of nucleus and into
cytoplasm
2. mRNA attaches to a ribosome
3. Transfer RNA (tRNA) decodes the mRNA and
brings amino acids to build up the protein
Anticodon (3 bases on
tRNA): Matches up to
codons on mRNA
4. Protein (chain of amino acids) detaches from
ribosome and goes off to work in the cell
GENETIC CODE

Code that matches codons in mRNA to amino
acids on tRNAs
