What else can I help you with?
What kind of molecule must be labeled to make radioactively labeled DNA?
Radioactive nucleotide
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.
Is radioactive waste a pure substance or a mixture?
Radioactive waste is nearly always a mixture but it is possible to be a pure substance.
What is laboratory technique in which the body radioactively labeled a substance is mixed with a blood specimen?
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.
Is plutonium a radioactive substance?
Yes
What kind of molecule must be labeled to make radioactively labeled DNA?
Radioactive nucleotide
What is the difference between a non-radioactive substance and a radioactive substance?
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.

What affect the half life of a radioactive substance A the mass of the substance B the temperature of the substance C the addition of a catalyst D the type?
A. The half-life of a radioactive substance is determined by the specific decay process of that substance, so it is not affected by the mass of the substance or the temperature. B. The mass of the substance does not affect the half-life of a radioactive substance. C. The addition of a catalyst does not affect the half-life of a radioactive substance. D. The type of radioactive substance directly determines its half-life, as different substances undergo radioactive decay at varying rates.
Is radioactive waste a pure substance or a mixture?
Radioactive waste is nearly always a mixture but it is possible to be a pure substance.
What is a radio substance?
A radioactive substance emit nuclear radiations.

Is plutonium a radioactive substance?
Yes
Is Pm a radioactive substance?
Pm is Prometheum. All isotopes of this element are radioactive.
What must be done to ensure DNA in a laboratory is radioactive?
Incorporating radioactive nucleotides must be done to ensure that DNA made in a laboratory is radioactive.
A substance labeled cayalyst is also known as?
A substance labeled as a catalyst is also known as a chemical agent that speeds up a reaction without being consumed in the process. Catalysts work by lowering the activation energy required for a reaction to occur and can be reused multiple times.
