Question

I have to do this project and I'm unsure of what it means when it tells me to make the chromosome? I know i have to draw it out but how do I do so and why the beads
1. Use ten beads and a centromere of one color to construct the long chromosome. Use ten beads and a centromere of a second color to construct the second chromosome in the long pair. Make a drawing of the chromosomes in the space below.
