Use the following information to answer the questions below.
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?

Question

The incorporation of radiolabelled nucleotides can be used to determine the timing and duration of the S phase, as this is when DNA synthesis occurs.
