Radioactive probes are molecules that are labeled with a radioactive isotope, such as ^32P or ^35S, which emit radiation that can be detected. They are commonly used in molecular biology to detect specific DNA, RNA, or protein molecules by binding to complementary sequences and producing a signal that can be visualized.
One molecule of glucose can produce 2 molecules of radioactive alcohol through the process of fermentation, where glucose is converted into ethanol and carbon dioxide by yeast.
Radioactive materials can emit radiation which can interact with nearby molecules, causing them to emit light. This phenomenon is known as Cherenkov radiation and is responsible for the glowing effect seen in some radioactive substances.
don't know
No. The sun is made up of a ball of gases, and the only radioactive gas we know of is Radon. Also, most radioactive elements are man-made.
A radiochemist studies the chemical properties and behavior of radioactive substances, including how they interact with other elements and molecules. They may investigate the production, detection, and applications of radioactive isotopes in fields such as medicine, environmental science, and nuclear energy.
Radiocarbon dating of organic samples is a biological application of radioactive isotopes. Another such application is the tagging of molecules with radioisotopes in order to investigate biological pathways, such as metabolism.
2 molecules=molecules 2 molecules= 2 molecules yayyy!!! We know stuff
All plants have radioactive waste, especially fossil fuel plants.
radioactive elements, tracers, are used in molecular research to investigate the movement of atoms and molecules through a biological system. At various intervals the movement of the radioactive atoms can be traced using photographic film.
Radioactive nuclides can ionize molecules in the air, breaking chemical bonds and creating free radicals. This ionization may lead to the formation of reactive species that can participate in chemical reactions, potentially altering the composition of the atmosphere and affecting health and the environment.
Molecules of a gas are in permanent motion.
