DNA

Deoxyribonucleic acid or DNA is the acid found in the nucleus of a cell, which contains the basic genetic instructions for the cell, e.g. how to grow, how to reproduce, etc. It is considered to be the "blueprint" of a cell, as it also contains the ultimate plan of how the cell will function, look, and what purpose it will fulfill. According to the theory of evolution, every time that a new offspring is conceived, the DNA of the new organism is ever-so-slightly changed, creating a new type of life form, but still very similar to its predecessor. The new genetic code gives a different order, which, say, will tell the cell to activate its lysosome under another condition, allowing for advancement in the life form. DNA is a particle comes in the form of a double-helix, constructed by molecules and some small clusters of atoms, which create the combination to the gentic code.
