The drawing shows two long rod-shaped structures with horizontal light and dark bands. how do these structures function in the inheritance of traits? the two long structures are genes made up of dna and the bands are chromosomes that can make individual proteins. b the two long structures are genes that contain dark rna bands that carry information for manufacturing proteins to the cytoplasm of the cell. c the two long structures are chromosomes that are made up of dna, and the bands include genes which carry information concerning how to make proteins. d the two long structures are made up of rna, and the light bands are made up of dna which carries information to the cytoplasm of the cell from the nucleus to make proteins.
