Protein synthesis

Question 1

Where are proteins made and using which sub-cellular structures?

Answer 1

• Proteins are made in the cytoplasm of cells on ribosomes
• Ribosomes use the sequence of bases contained within DNA to make proteins

Question 2

What is the process of protien synthesis?

Answer 2

• DNA cannot travel out of the nucleus to the ribosomes (it is too big to pass through the nucleus pores)
• Instead, the base code of each gene is transcribed onto mRNA (messenger RNA)
• The correct sequence of amino acids is bought to the ribosomes and joined together
• The amino acids fold up to form a protein
