Synthesis Process
Biology: Cambridge International GCSE Supplement, topic 17.1.6
Protein Synthesis
The process of protein synthesis (creation) happens like this:
Template taken
- A template made from mRNA (a polymer similar to DNA) is taken from the DNA and leaves the nucleus.
Template used
- The mRNA template is used to guide protein synthesis on ribosomes located in the cytoplasm.
Delivery of amino acids
- Specific amino acids are delivered by carrier molecules to the protein chain, where they are added in the order shown on the template.
Unique structure created
- Once complete, the long protein chain folds up, giving it a unique structure.
- This unique structure is essential to the protein’s function, in the form of enzymes, hormones, or structural proteins (e.g. collagen).
