Nucleolides can be radiolabeled before they are and can therefore be assayed to track their incorporation. in a set of experiments, a student-faculty research team used labeled T nucleotides and introduced these into culuture of divind human cells at specific times. the research team used the setup to study the incorporation of labeled nucleotides into a culture lymphocytes and found that the lymphocytes incorporated the labeled nucleotide at significantly hgher level after a pathogen was introduced into the culture. what conclusion can be drwan about the infect cells?
