Vedclass · Answer

(C) To measure $DNA$ synthesis precisely,scientists use radioactive labeling of nucleotides that are specifically incorporated into $DNA$ strands.$DNA$ contains the nitrogenous base $Thymine$,whereas $RNA$ contains $Uracil$.Therefore,radioactive $Thymine$ (often labeled as $^3H-Thymine$) is used to specifically track $DNA$ synthesis without interference from $RNA$ synthesis.This technique is commonly used in experiments like the pulse-chase labeling to study the cell cycle and replication.
