Which of the following is used in the treatment of blood cancer?
A. 1131{1^{131}}
B. P32{P^{32}}
C. RnRn
D. I127{I^{127}}

Explanation

Solution

The element phosphorus in its radioactive form. It's used to mark DNA and proteins in the lab. It was previously used to treat polycythemia vera, a blood condition, and certain kinds of leukaemia, but it is no longer widely used. Phosphorus−32Phosphorus - 32 emits radiation that destroys a cell's DNA, potentially causing the cell to die.

Complete answer:
Phosphorus−32 (32P)Phosphorus - 32{\text{ }}\left( {32P} \right) is a phosphorus isotope that is radioactive. Phosphorus−32Phosphorus - 32 has 15 protons and 17 neutrons in its nucleus, one more than the most prevalent phosphorus isotope phosphorus−31phosphorus - 31 . Phosphorus−32Phosphorus - 32 is only found in trace amounts on Earth due to its short half-life of 14 days and quick degradation.
Phosphorus is abundant in many organic molecules, therefore Phosphorus−32Phosphorus - 32 can be used to trace phosphorylated compounds (for example, in elucidating metabolic pathways) and radioactively mark DNA in medicine, biochemistry, and molecular biology.
Phosphorus−32Phosphorus - 32 can be tracked from outside the body to pinpoint the location of potentially cancerous tumours. Phosphorus−32Phosphorus - 32 emits radiation that can be used for both medicinal and diagnostic purposes. The use of 32P−chromic phosphate{}^{32}P - chromic{\text{ }}phosphate as a prospective chemotherapeutic treatment for disseminated ovarian cancer has been investigated. In this case, the therapeutic effect is due to the long-term damaging consequences of beta radiation from Phosphorus−32Phosphorus - 32 accumulating in malignant cells. Phosphorus−32Phosphorus - 32 is commonly used to identify and treat cancer, particularly in the eyes and skin.
So, the correct option is: (B) P32{P^{32}} .

Note:
In plant sciences, Phosphorus−32Phosphorus - 32 is used to follow a plant's fertiliser intake from the roots to the leaves. The Phosphorus−32Phosphorus - 32 -labeled fertiliser is applied to the plant hydroponically or through water in the soil, and the phosphorus utilisation may be calculated using the released beta radiation.
