DNA pulse labeling
= DNA pulse labeling
{c}
<DNA pulse labeling> exposes <biological cells> to a detectable precursor for a bounded interval. After removal, later sampling can follow the labeled material and descendants. A short pulse asks about synthesis during that interval; overnight labeling instead accumulates evidence across many hours. Detectable synthesis does not by itself prove completion of a <cell cycle>, and <DNA repair> can also incorporate precursors.
