Nucleotides can be radiolabeled before they are incorporated into newly synthesized dna and, therefore, can be assayed to track their incorporation. in a set of experiments, a student-faculty research team used labeled t nucleotides and introduced these into a culture of dividing human cells at specific times. which of the following questions might be answered by using the method described?
a. when do spindle fibers attach to chromosomes?
b. how many picograms of dna are made per cell cycle?
c. what is the length of the s phase of the cell cycle?
d. how many cells are produced by the culture per hour?
