Protein Synthesis
Biology: AQA GCSE Higher, topic 6.1.12
Protein Synthesis
Protein synthesis is how our bodies make proteins.
Codon
- Each amino acid is coded for by a specific sequence of three bases (called a codon).
Order of bases
- The order of the bases on the DNA tells us the order for combining amino acids to create particular proteins.
Different proteins
- We can change the protein made by a gene by altering the sequence of bases in that gene.
Test yourself on Protein Synthesis
A section of DNA contains 30 bases. How many amino acids could this section code for?
If the order of bases on DNA changes, what happens to the proteins made using the DNA?
These structures are all involved in protein synthesis. Which of each pair is the smaller unit?
What does protein synthesis do in the body?
Which statement correctly links the sizes of bases, amino acids and proteins in protein synthesis?
