RNA has great capability as a genetic molecule; it once had to carry on hereditary processes on its own. It now seems certain that RNA was the first molecule of heredity, so it evolved all the essential methods for storing and expressing genetic information before DNA came onto the scene.
Diffusion occurs because of the movement of molecules from the region of higher concentration to the region of lower concentration. This movement of molecules occurs due to a thermal motion. Diffusion normally occurs between two compartments having difference in concentration. In case of fluid it moves from the region of higher concentration to the region of concentration until a balance is reached. The process of diffusion is very important for the humans as well. The oxygen that humans breathe in gets diffused with the blood.<span>

Answer:
It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made ... form that can be used by cells to produce the proteins needed to support life. ... In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing.
