Because If they don't, the scientists won't know what the difference is in.Example:You have two glasses of water. One is labeled control.The other is labeled salt. The one labeled controlhas nothing added to it. The one labeled salt has salt added to it. Is there a difference between the two glasses?If an experiment has a control in it, that means the scientist needs to know if there is a difference in the experiment.
The amplitude of a wave is generally labeled 'A'.
Its possible it kills all of the germs, probably it did in many trials however in some cases it cannot in which it must be labeled 99 percent.

The DNA separated into two classes: labeled DNA and unlabeled DNA. The labeled DNA contains the radioactively labeled nucleotides that were incorporated during DNA replication, while the unlabeled DNA represents the original, non-radioactively labeled DNA from the bacteria. The centrifugation process separated the DNA based on density, with the heavier labeled DNA migrating to a higher position in the centrifuge tube compared to the unlabeled DNA.

Radioactively tagged bacteriophages are used to confirm that DNA, not protein, is injected into host cells during infection. The radioactively labeled DNA can be detected inside the host cells after infection, providing evidence that DNA is the genetic material transferred by the bacteriophages. This experiment was crucial in establishing DNA as the genetic material in organisms.
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.
scientist wanted a starting point that was labeled 0 degrees.
The laboratory technique you are referring to is known as radioimmunoassay (RIA). In RIA, a radioactive substance is used to label a specific molecule or antigen, and when this labeled molecule is mixed with a blood specimen containing the corresponding antibody, the level of radioactivity can be used to quantify the amount of antigen present in the blood sample.
Dideoxynucleotides have no OH group on the sugar of the nucleotides, only H's. That means phosphate groups can't react with the sugar to form a phosphodiester bond to join two nucleotides together, so DNA syntheses is terminated
