Answer:
Incorporating radioactive nucleotide must be done to ensure DNA made is a laboratory is radioactive
Step-by-step explanation:
Radioactive nucleotide are generally used in the detection of some specific nucleic acid series. These are the typically incorporated inside the DNA and RNA series for detection as well as analysis. These nucleotide involves radioactive phosphates, digoxygenin, biotin, fluorophores and enzymes. It was first used in 1935 by George de Hevesy. P32 and S35 labelled as the nucleic probes and now the phosphates is being in large use. Hydrogen can also be used in-situ hybridisation which gives greater resolution and less sensitive in long exposure.
