You perform an experiment by incubating a radiolabeled nucleotide into the medium of a culture of cells. The cells that take up the radiolabel would be expected to be in what phase of the cell cycle? A) S phase B) G₁ phase C) G₂ phase D) M phase

Question

Quizplus · Accepted Answer

During S phase, DNA replication occurs and new nucleotides are incorporated into newly synthesized DNA strands. Therefore, cells in S phase actively incorporate nucleotides into their DNA and would be the most likely to take up radiolabeled nucleotides in this experiment.
