Suppose that the experiment described in Problem 10.7 was carried out again, except this time replacing the ³H-thymidine with nonradioactive thymidine at the same time that the colchicine was added (after one cell generation of growth in ³H-thymidine-containing medium). The cells were then maintained in colchicine plus nonradioactive thymidine until the metaphase shown in Problem 10.7 occurred. What would the autoradiographs of these chromosomes look like?
