Examples of Nucleic Acids. Nucleic acids, best-known as DNA and RNA, are often termed "the building blocks of life." These building blocks are found in the nuclei of cells and help proteins to be built, help cells to replicate, govern heredity and the cell's chemical processes.

Neurotransmitter will create a chemical change inside our body as a response to each situation that we face. This response then will be transmitted toward our body and will determine what we should do next, (this process will be a lot easier to observe during dangerous fight or flight situations)
