What is a gene?
A gene is a section of DNA. It contains the instructions to make a specific protein.
What do they do?
Cells make proteins by stringing aminno acids together in a particular order.
Amino acids and proteins
Only 20 amino acids are used, but they make up thousands of different proteins.
Genes tell cells in what order to put the amino acids together.
DNA also determines what proteins the cell produces and that determines what type of cell it is.
