All living organism pass information from one generation to the next with genetic material containing the information needed to construct a complete organism. The number of genes vary from organism to organism. The gene is the unit of genetic infomation.
More complex organisms require a greater number of genes to perform life functions.
A gene does not function autonomously, but relies upon other cellular components for its function. All cellular activities obey the known laws of physics and chemistry. All genes regardless of the type of organism are made of the same basic building blocks called nucleic acids.
