Nucleus and DNA
just like the human body,there are many parts in a cell.In order to survive cells rely on tiny specialized parts within them. These special "mini-cells" help the cell do certain jobs or functions.The most important "mini- cell" of all is the nucleus. The nucleus is like the air traffic control center at an airport. It controls the functions of everything inside the cell. Inside the nucleus is DNA. DNA can determine millions of factors including your height eye color blood type and even your personality.
