A car has many parts that work together to ensure it runs efficiently, just like a cell. Many individual components must work in harmony for the cell to function properly. An important part of any car is the engine. The engine makes the car move faster or slower, but the gas pedal is what controls speed. Similarly, an important part of any cell is the DNAThe blueprint of a cell that controls the function of all components within the cell; deoxyribonucleic acid. DNA is the blueprint of the cell that contains all of the information needed to control the cell. The DNA influences what the cell does and how it behaves, just like the gas pedal.
