What do genes contain?

What do genes contain?

• A. All the instructions necessary to create the human body
• B. Only the blueprint for hair color
• C. A list of foods
• D. The recipe for digestion

Answer: (A)

Genes hold the instructions for making the molecules that run and shape the body. These instructions are encoded in DNA and are used to produce proteins and RNA, which are the workhorses inside cells. Proteins act as enzymes, structural components, receptors, and signaling molecules, driving development, growth, and everyday function. That’s why the option saying genes contain all the instructions necessary to create the human body is the best fit: it captures the idea that genetic information provides the blueprint for building the body's components and guiding its formation. The other choices miss the role of genetic information—hair color is only one trait influenced by many genes; a list of foods isn’t genetic information; a digestion recipe isn’t directly stored as a simple directive in genes.
