For information to flow properly, it must be stored, transmitted, and used.

For information to flow properly, it must be stored, transmitted, and used.

• A. Energy
• B. Stored, transmitted, and used
• C. Decay
• D. Stored and used

Answer: (B)

Information in biology moves through a system only when it is stored, transmitted, and used. Storage keeps the information in a stable form, such as DNA. Transmission passes that information along to daughter cells or through cellular signaling so it can reach the right places. Use then converts that information into action, through processes like transcription and translation that produce proteins and other functional products. If any of these steps are missing, the information cannot guide the system properly. Energy is needed for processes, but it doesn’t by itself describe how information is preserved and passed along; decay is not a required component of information flow, and storing plus using omits the essential transmission step.
