What term best describes the molecules that contain the instructions for producing proteins that regulate body processes and influence traits such as intelligence?

• A. Chromosomes
• B. Genes
• C. DNA
• D. Proteins

Answer: (B)

The main idea is that genes are the units that carry the instructions for making proteins. A gene is a specific sequence of DNA that is transcribed and translated into a protein, and those proteins regulate countless body processes and help shape traits, including cognitive aspects like intelligence. DNA stores all genetic information, while chromosomes are the structures that organize and carry many genes inside the cell nucleus. Proteins are the products of gene expression, not the instructions themselves. So, genes best fit the description because they are the defined instructions that guide the production of proteins which influence biological regulation and traits.
