DNA is labeled a radioactive phosphorus because when Alfred looked at the examples 32p always pelleted with bacteria but the new Phage made by these infected bacteria contained Radioactive 32p which is why its labeled Radioactive phosphorus.
The reaction that is commonly used to radioactively label DNA is the nick translation method, where a DNA molecule is treated with a DNA polymerase, dNTPs (including radioactive ones), and a DNAase to create radioactive labeled DNA fragments.
Synthesis of new DNA.
The substrates used in the DNA synthesis reaction are deoxyribonucleoside triphosphates (dNTPs), which are the building blocks of DNA.
Recombinant DNA technology PCR
Polymerase chain reaction (PCR) is a commonly used method to amplify small DNA samples. In PCR, the DNA sample is heated to separate the double-stranded DNA into single strands, then specific primers are added to flank the target DNA sequence. DNA polymerase then synthesizes new DNA strands complementary to the target sequence, resulting in exponential amplification of the DNA fragment.
The reaction used to radioactively label DNA is typically performed using a DNA polymerase enzyme along with radioactive nucleotides, such as [α-32P]dNTPs. This allows for the incorporation of the radioactive label into the DNA strand during the polymerase reaction.

PCR
polymerase chain reaction (PCR)
DNA fingerprinting uses variants in DNA sequences to create a unique profile for each individual, while the Polymerase Chain Reaction (PCR) is a technique used to amplify specific DNA sequences. PCR is commonly used in DNA fingerprinting to amplify regions of interest in the DNA sample before further analysis. This amplification step allows for better detection and characterization of DNA variations used in DNA fingerprinting.

no, it is used to separate different sized pieces of DNA using a gel and an electric current. Polymerase Chain Reaction (PCR) is the multiplication of DNA with the use of a PCR machine, enzymes and primers. The PCR machine allows the multiplication of DNA through temperature changes, activating each step of the reaction and copying DNA millions of times.
