When metaphase chromosomes are stained with dye, they show a pattern of dark and light bands; each chromosome's band pattern is unique but consistent to that chromosome, and each gene within a chromosome is regularly located within the same band. Which of the following indicates what this tells us about chromosome organization?

MCQs on the cell and its structures, including molecular compounds, structural features, and organelles including the nucleus, cytoskeleton, and extracellular matrix. Particular emphasis on transport mechanisms and membrane trafficking, cellular signaling, the cell cycle including mitosis and meiosis, and gene expression.
