These elements exist in the form of molecules and organelles â picture them as the tools, appliances, and inner rooms of the cell. Major classes of intracellular organic molecules include nucleic acids, proteins, carbohydrates, and lipids, all of which are essential to the cell's functions. Nucleic acids are the molecules that contain and help express a cell's genetic code. There are two major classes of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
These strands, called chromatin, contain the genetic material, the instructions that direct the functions of a cell. For example, the instructions in the chromatin ensure that leaf cells grow and divide to form more leaf cells. The genetic material is passed on to each new cell when an existing cell divides. Bacterial cells do not have nuclei, so you are correct, their DNA is located in the cytoplasm.
