Proteins are labeled with radioactive amino acids so that they can be identified. Scientists use radioactivity to label proteins in order to track them during their experiments, you can follow protein degradation, label proteins that don't have antibodies, label all proteins produced at a certain time, separate proteins produced by intracellular pathogens from host proteins, among many other uses.

Why did the scientists use radioactive sulfur and phosphorus in this experiment?
Scientists used radioactive sulfur and phosphorus in this experiment to track the movement of these elements within the cell. By incorporating radioactive isotopes of sulfur and phosphorus into molecules like proteins or nucleic acids, they could follow their distribution and activity, providing valuable insights into cellular processes.
What molecule contains carbon hydrogen oxygen and nitrogen which is used by the body for growth and repair?
Protein is the molecule that contains carbon, hydrogen, oxygen, and nitrogen and is used by the body for growth and repair. It is composed of amino acids that are essential for building and repairing tissues in the body.
Examples of radioactive tracing used in agriculture?
Radioactive tracing in agriculture is used to study nutrient absorption in plants, soil movement, and pesticide uptake. For example, radioactive isotopes of phosphorus are used to study the uptake of phosphate by plants, while carbon-14 can help trace the movement of carbon in soil. Additionally, radioactive isotopes can be used to study the degradation of pesticides in the environment.
What element is used for storing and transporting radioactive materials?
Lead is commonly used for storing and transporting radioactive materials due to its density and ability to block radiation. Lead containers can shield against harmful radiation emitted by radioactive materials, making it a suitable choice for safety purposes.
What is Radioactive dating of rock samples?
Radioactive dating of rock samples is a method used to determine the age of rocks and minerals by measuring the decay of radioactive isotopes within them. By analyzing the ratios of parent and daughter isotopes in a rock sample, scientists can calculate the amount of time that has passed since the rock formed. This technique is commonly used in geology and archaeology to establish the age of Earth materials.
Why did Hershey and Chase grow viruses in cultures that contained both radioactive Sulfur. What might have happened if they had used only one radioactive substance.?
Hershey and Chase used radioactive Sulfur to label viral proteins, as proteins contain sulfur. By growing the viruses in a culture containing both radioactive Sulfur and Phosphorus, they could differentiate between viral proteins (labeled with Sulfur) and viral DNA (labeled with Phosphorus). If they had only used one radioactive substance, they would not have been able to determine the specific molecule (protein or DNA) that the virus injected into the host cell.
Radioactive sulfur was used to label the ... in viruses?
phase. I think
What of the following reactions is used to radioactively label DNA?
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.
What is radioactive labelling?
Radioactive labeling is a technique used to track the movement of molecules in biological systems. It involves attaching a radioactive isotope to a molecule of interest, such as a protein or nucleic acid, which emits radiation that can be detected using specialized equipment. This allows researchers to study the behavior of the labeled molecule in cells or tissues.
Which molecule for which phosphorus-32 is used as a radioactive marker?
Dna
What has an isotope mass of 32 and is used to label proteins?
sulfur
A radioactive element is sometimes used to trace the pathway of chemical reactions in the cell If newly synthesized proteins are radioactive the radioactive element used could be?
The radioactive element used to trace the pathway of chemical reactions in cells for newly synthesized proteins is typically sulfur-35 (35S) or carbon-14 (14C). These isotopes are incorporated into proteins during synthesis, allowing researchers to track their movement and interactions within the cell.
What molecule is used to make radioactivity labeled DNA?
Radioactive nucleotide
What reaction is used to radioactively label DNA?
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.
What did Hershey and Chase used to radioactively label the T2 phage's proteins?
32P
What is radioactive yellow II label?
The radioactive yellow II label is a symbol used to indicate materials that are radioactive and pose a health hazard. It is typically a yellow triangle containing the radiation symbol and is used to warn individuals of potential exposure to radiation in the area. It is important to follow safety protocols and handle these materials with care.
Used to label DNA and protein in experiments?
Fluorescent dyes are commonly used to label DNA and protein in experiments. These dyes emit light when exposed to specific wavelengths of light, allowing for visualization and analysis of the labeled molecules. Additionally, radioactive isotopes can also be used for labeling, but they may pose safety and disposal challenges.
