Chapter 10. Protein Synthesis. DNA has the code to make proteins. DNA contains the instructions for the cell: It tells it how to make copies of cells: Body (somatic) cells are copied by mitosis Sex cells are copied by meiosis

The tRNA attaches AMINO ACIDS together to FORM PROTEINS
A. DNA uncoils when RNA POLYMERASE combines with a PROMOTER and they tell the DNA to unwind.
B. The PROMOTER puts the mRNA nucleotides together along the DNA strands, adding the complementary bases and proofreading them.
A. mRNA gives the message to the t RNA
This is called TRANSLATION
B. The tRNA carries Amino Acids on it (every 3 bases on tRNA has an amino acid attached - these are called CODONS)
C. The tRNA attaches AMINO ACIDS together to FORM PROTEINS
This is called Protein Synthesis
tRNA with amino acid attached
Protein formed from amino acids
