If you expose HeLa cells to 3H-thymidine just as they enter S phase, then wash this material off the cells and let them go through a second S phase before looking at the chromosomes, how would you expect the 3H to be distributed over a pair of homologous chromosomes?Would the radioactivity be in (a) one chromatid of one homolog, (b) both chromatids of one homolog, (c) one chromatid each of both homologs, (d) both chromatids of both homologs, or (e) some other pattern?
Choose the correct answer and explain your reasoning.
