All of the statements are correct. Genes are segments of DNA that serve as the basic units of heredity. They contain the instructions for building and functioning of various molecules in the body, including proteins. These genes code for specific traits, such as eye color, height, or hair texture. Traits, therefore, are determined by the genes we inherit from our parents and are composed of DNA molecules.
