Is phosphorescence radioactive?
Ordinary phosphorus found in nature is not radioactive. Like all other elements, radioactive synthetic isotopes of phosphorus have been made.
What is the role of radioactive phosphorus in DNA technologies?
To make DNA probes
What radioactive isotope did hershey and chase use to tag phage DNA?
phosphorus - 32P
How would the results of the hersheychase experiment have been different if protein were the genetic material?
The experiment would simple prove them wrong and prove that DNA is the genetic carrier.
In the Hershey and Chase experiment that helped confirm that DNA not protein was the hereditary material the key finding was that?
The correct answer is: Radioactively labeled phosphorus was present inside the infected bacteria.
33P is a radioactive isotope of phosphorus. Can 33P be used to make a radioactive nucleotide?
Yes because it can replace the phosphorus atom in the phosphate group.
What happens when T2 phages are grown in the presence of radioactive phosphorus?
The bacterial proteins will become radioactive
Is phosphorus explosive radioactive or noxious?
yes it is
Is phosphorescence radioactive?
Ordinary phosphorus found in nature is not radioactive. Like all other elements, radioactive synthetic isotopes of phosphorus have been made.
What isotope iodine iron phosphorus radium has the longest half-time?
Phosphorus, iron, and iodine all have at least one isotope that is stable, and any of these would do for the longest half life. In fact, the radioactive isotopes of phosphorus are all synthetic, so radioactive phosphorus is not found in nature.
Which molecule for which phosphorus-32 is used as a radioactive marker?
Dna
What is the role of radioactive phosphorus in DNA technologies?
To make DNA probes
How do you perform cold flame experiment with phosphorus?
cold flame forms
What are phosphorus's common isotopes?
Phosphorus is considered practically monoisotopic: P-31; radioactive isotopes P-32 and P-33 exist only in traces.
What radioactive isotope did hershey and chase use to tag phage DNA?
phosphorus - 32P
What reaction is used to radioactivley label DNA?
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.
What are phosphorus's used for?
There are many uses of phosphorus such as: 1. Phosphates are used to make special glass which is used for sodium lamps 2. Plants needs phosphorus for nutrition. Thus, it is added in fertilizers; 3. Radioactive isotopes of phosphorus are used as radioactive tracers; 4. China ware are made up of calcium phosphate 5. Matchstick strikers are made up of phosphorus 6. Incendiary Bombs, Tracer Ammunition, and Smoke Screen are made up of white phosphorus 7. One compound of phosphorus called tributylphosphate is used for extracting uranium 8. DNA and RNA makes use of phosphorus 9. Phosphorus is also used in manufacturing steel 10. It is used as detergent (Sodium tripolyphosphate) 11. Used for manufacturing fertilizers, toothpaste, food additives and pesticides (0ther compounds of Phosphorus)
