What did Hershey and Chase show the genetic material of the t2 bacteriophage was?
DNA is the genetic material. However, Hershey-Chase also stated that some little sulfur containing material also entered the bacterial cell. Looking at these two conclusions, Hershey-Chase could not reach a definite conclusion as to whether DNA or Protein contains the genetic material. The conclusion came from Watson-Crick who stated that the sulfur containing material could have entered the cell due to the fact that DNA replication and subsequently translation of the mRNA leads to the synthesis of sulfur containing protein which were found in the bacterial cell.
What does PET stand for brain scan?
PET stands for Positron Emission Tomography. It is an imaging technique used to visualize metabolic processes in the brain by detecting the distribution of a radioactive tracer. This scan is often used to examine brain function and diagnose conditions such as tumors or neurological disorders.
Who is experiment demonstrated that DNA is the molecule of heredity?
The experiment that demonstrated DNA as the molecule of heredity was conducted by Alfred Hershey and Martha Chase in 1952. They used bacteriophages, which are viruses that infect bacteria, to show that genetic information was carried by DNA, not protein.
What kind of tracer is used in a bone scan?
Radio active
What are the radioisotopes that attach themselves to red blood cells?
tracer
How does radioactive tracer get into the body?
They dissolve it in a liquid and the patient drinks it
How much radioactive tracer is injected into the vein for a typical bone scan?
About 1 Mg.
Which radioactive tracer showed up in the bacteria that led Hershey and Chase to their conclusion that DNA not Protein was the genetic material?
According to my bio book, I think it's Alfred Hershey and Martha Chase, in the HERSHEY-CHASE experiment.
Nuclear medicine uses these to image organs for diagnosis and treatment?
radioactive material called a tracer
Would a substance with a one second life be effective as a radioactive tracer?
the dog ate the bacon
Radioactive isotopes that can be followed through a chemical reaction or a industrial process is?
Tracers.
What is a radioactive tracer and give an example of how one might be used?
A radioactive tracer is a radioactive atom inserted in a compound to see what happens to it in a reaction, usually in biotechnology. For example, to find out where carbon atoms go in photosynthesis, scientists can give the plants carbon dioxide with carbon-14 instead of carbon-12 and track the progress of the carbon-14.

A tracer is a radioactive element whose pathway through the steps of a chemical reaction can be followed?
Yes a tracer is a radioactive element whose pathway through the steps of a chemical reaction can be followed. It can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products.
How dangerous is technetium?
Technetium is not really dangerous. Since doctors will often use Technetium 99 as a radioactive tracer. It may be radioactive but its decay is slow and will produce a minute amount of gamma rays.
Four uses of radioactive isotopes are?
- energy source - radiation source - tracer - fuel for nuclear reactors - explosive for nuclear bombs
