Answer:
<h2>C. What is the length of the S phase of the cell cycle?
</h2>
Explanation:
- Such type of technique that is used to tack or identified the passage or location of the metabolic reaction, organelles and some other during the research or experiment is known as radiolabelling.
- During the study of the synthesis of the DNA, the nucleotides are labeled to check the S phase of the cell cycle.
- Since the synthesis of the DNA takes place during this phase so the time and length of the S phase can be easily obtained during the experiment.
- This technique is also used for different purposes during the biomolecular experiment and some other disciplines.
