What 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.
The bursting of the cell releases new bacteriophage .?
When a cell bursts, it releases new bacteriophages that were produced inside the cell. These bacteriophages can then infect other bacterial cells, continuing the cycle of infection and replication. This process is known as a lytic cycle in bacteriophages.
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.
Viruses that infect bacteria are?
called bacteriophages. They are viruses that specifically infect and replicate within bacteria, ultimately leading to the death of the host cell. Bacteriophages play a crucial role in controlling bacterial populations in various environments.
Can plasmids or bacteriophages be used in vaccines to fight bacteria?
Yes, plasmids can be used in DNA vaccines to fight bacteria by expressing antigens that trigger an immune response. Bacteriophages can also potentially be used in vaccines by delivering antigens or genes into host cells to stimulate an immune response against bacteria.

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.
Bacteria that invade a host organism and obtain nutrients from hosts cells?

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 types of organisms does bacteriophage attack?
Bacteriophages are viruses that infect and replicate within bacteria. They do not infect human cells or other eukaryotic organisms. Bacteriophages are specific to infecting particular bacterial species or strains.
Do virus pickup and carry genes from their host cells?
Yes, viruses can pick up and carry genes from their host cells through a process known as transduction, particularly in bacteriophages. When a virus infects a host, it may inadvertently incorporate bits of the host's DNA into its own genome. This can lead to genetic transfer between different organisms, potentially influencing the evolution of the host or contributing to genetic diversity. This phenomenon is particularly significant in horizontal gene transfer among bacteria.
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.
What is the function of the tail pins in the bacteriophages?
Tail pins in bacteriophages help the virus attach to the host bacterial cell by interacting with specific receptors on the cell surface. Once attached, the tail pins facilitate the injection of the viral genetic material into the host cell for replication.
