Final answer:
Proteins are directly related to genes and are instrumental in numerous biological functions including acting as enzymes and hormones, contradicting statement A) proteins are not related to genes.
Step-by-step explanation:
Proteins are essential biological molecules that are deeply interconnected with genetic information and biochemical reactions. They are composed of amino acids and have myriad functions within organisms.
The statement that is not true about proteins is A) proteins are not related to genes. In fact, proteins are the direct products of the expression of genes, with DNA serving as the blueprint for protein synthesis.
Proteins can indeed act as hormones or be enzymes that catalyze various reactions, and through these functions, they can influence but not explicitly cause specific behaviors.
