Avery are radioactively tagged bacteriophages to discover that DNA, not protein is injected into host cells.

Radioactively tagged bacteriophages are used to confirm that DNA, not protein, is injected into host cells during infection. The radioactively labeled DNA can be detected inside the host cells after infection, providing evidence that DNA is the genetic material transferred by the bacteriophages. This experiment was crucial in establishing DNA as the genetic material in organisms.

What did hershey and chase know about bacteriophages that led them to use these viruses in their DNA experiment?
Hershey and Chase knew that bacteriophages infect bacteria by injecting their DNA into the host cell. This led them to use bacteriophages in their DNA experiment to confirm that DNA, not protein, is the genetic material responsible for heredity. By radioactively labeling the DNA and proteins of the virus, they were able to trace the genetic material through the infection process.
What do most bacteria phages consist of?
Most bacteriophages consist of a protein capsid that encapsulates the phage's genetic material (either DNA or RNA). Some bacteriophages also have a tail structure that helps them attach to and infect bacterial cells.
What did hersey and chase discover?
Hershey and Chase's experiments in 1952 provided evidence that DNA, not protein, is the genetic material in bacteriophages. They used radioactive isotopes to track the transmission of DNA and protein from the phage to the bacteria during infection, showing that it was the DNA that carried the genetic information.
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.
How do the structures of bacteriophages help them infect the host?
Bacteriophages have a protein coat that helps them recognize and attach to specific receptors on the bacterial cell surface. They also have a tail structure that injects their genetic material into the host bacterium. These structures enable the bacteriophages to efficiently infect the bacterial cell and take over its machinery for replication.
What results of OT Avery's experiments indicated that genes were not special types of protein molecules?
bacteriophages injected DNA into cells to replicate instead of protein
Do bacteriophages have glycoproteins?
No, bacteriophages do not have glycoproteins. They are composed of a protein coat that surrounds their genetic material (DNA or RNA) and do not contain the complex sugars found in glycoproteins.

Most bacteriophages consist of only a coat and a core?
Yes, bacteriophages consist of a protein coat (capsid) that encloses their genetic material (DNA or RNA) core. The capsid helps the virus attach to and enter host bacterial cells.
Do bacteriophages multiply and how?
They do multiply and it's accomplished by injecting DNA into a host cell (bacteria in this case) and forcing the cell to synthesize the virus DNA, effectively creating more bacteriophages with the bacteria's own protein. The bacteria eventually bursts and the new bacteriophages are released to live happily ever after.
Where is the ppd injected?
Purified Protein Derivative (PPD) is injected intradermally (between the layers of the skin).

When DNA from a virus is injected into a bacterium the bacterium produces viral protein?

How did Hershey and Chae's use of radiolabeled bacteriophages to study the genetic material validate Avery's research?
Hershey and Chase's use of radiolabeled bacteriophages demonstrated that DNA, not protein, is the genetic material. This supported Avery's earlier research that implicated DNA as the carrier of genetic information. The radiolabeled phages showed that only the DNA component, not the protein component, entered bacterial cells and played a role in reproduction.
Is insulin lipid or water soluble?
No it is not a lipid. Insulin is made up of proteins. It cannot be injected orally.
