Nucleotides can be radiolabelled before they are incorporated into newly forming DNA and can therefore be assayed to track their incorporation.In a set of experiments,a student-faculty research team used labelled T nucleotides and introduced these into the culture of dividing human cells at specific times.
-Which of the following questions might be answered by such a method?
A)How many cells are produced by the culture per hour?
B)What is the length of the S phase of the cell cycle?
C)When is the S chromosome synthesized?
D)How many picograms of DNA are made per cell cycle?
E)When do spindle fibres attach to chromosomes?
