nature : to regulate and control the activities of life signal. General information can be divided into genetic, neurological and sensory information, chemical information. (1) genetic information in the form of passwords stored in the DNA molecule, DNA replication transmitted to the offspring. In the process of growth and development of future generations, the genetic information from DNA to RNA transcription, and then translated into a protein specific to the implementation of various life functions. (2) neurological and sensory information on electrical pulse and neurotransmitters carry and transmit. Nervous system to accept the internal and external environment of information, processing, conditioning and control of all parts of the body function. (3) While the first two are the carriers of information of chemical substances, but usually referred to the chemical information will be in addition to the above two categories of substances by chemical messages of the media. The various organisms function in an orderly way, the environment will react in a timely manner, it is because of the existence of organisms through a variety of chemical elements pass information to the information system. Biological information on the survival of living organisms to multiply, play an important role, it is material, energy together constitute organisms into three major factors.
