How Proteins are Made

• Made from long chains of amino acids (20)
• DNA bases are read as triplets
• DNA is found in the nucleus
• Protein synthesis happens on ribosome in cytoplasm
• mRNA carries information from DNA to ribosome
• When a protein is made, mRNA is made in the nucleus, copying the base sequence
• mRNA moves out of the nucleus into the cytoplasm and attaches to the ribosome
• ribosome assembles amino acids into protein molecules
• the specific order of amino acids is determined by the sequence of bases in the mRNA
