What effect might conjugation have on the offspring of the bacteria that underwent conjugation?
Bacteria take DNA from their environment.Bacteria inject DNA into another cell
How might a bacteriophage prove to useful?
It helps us digest our food. It helps us break down the food particles so that we can absorb them
During conjugation which what structures does a bacteria form that is used to transfer DNA?
conjugation occurs between two bacterial cells and transfers DNA in the form of plasmids. this is one way to transfer of genetic material - it is not sexual reproduction, The other two ways to transfer genetic material between bacteria are transformation and transduction. In order to be able to perform coagulation (transfer of a plasmid) the bacteria must have an F factor (DNA that codes for the PILI protein, which allows the bacteria to create a bridge through which the bacteria inject the plasmid to another bacteria). Bacteria with F factor is called F+, and without it is called F-. F+ can transfer the plasmid to an F- bacteria.
How are viruses harmful to living cells?
Viruses can reproduce very quickly. When reproducing they enter a living cell and they inject their genetic material.
Which is the smallest out of yeast or viruses or bacteria?
Viruses are, by far, the smallest. Bacteria and yeast cells have a complete cell structure, including the nucleus and all of the other parts of a cell. Viruses don't, so they have to inject their 'material' (I don't remember the name of the inside the virus) into the 'host' cell and force it to duplicate the viruses, which kills the host cell.
What is the pathogen attacks specific cells and injects genetic materials?
Viruses attach specific cells and inject genetic material. There are viruses called bacteriophages that infect bacteria be injecting their genetic material into the bacterial host and invading their protein machinery. With animal viruses that infect animal cells (much larger than bacteria), the virus either injects genetic material OR gets into the cell whole before it begins to unleash its pathogenic effects
When a virus infects a bacterium what does the virus inject into the cell?
It's genetic material and some enzymes sometimes which hijack the bacteria into making more viruses.
What does bacteriophage inject into a cell?
A bacteriophage ("eater of bacteria") inject their DNA (or RNA) into the cell.
Can virus get a bacteria?
Yes- Bacterial viruses are called bacteriophages. Some examples are T4 and T7 phages. They are complex DNA viruses that attach themselves to the cell surface and then inject their DNA to the inside of the bacteria. Bacteria have enzymes called restriction enzymes that cleave DNA at specific sites called restriction sites. These enzymes are the bacterium's defense against phages.
Is neptunium good or bad to inject into the body?
Neptunium is a dangerous material !
What effect might conjugation have on the offspring of the bacteria that underwent on conjugation?

Which best describes transduction in bacteria?
Bacteria transfer DNA with a bacteriophage.
What is the Injection Unit is responsible for injection molding machine?
It is responsible for material charging and injection. It helps inject the material into the mould.
What is the best way to diagnose a patient?
you have to inject a person with that particular bacteria or virus in a weak form
What are the main differences between a virus and a bacteria which enable scientists to classify them?
Bacteria are single-celled organisms that can replicate themselves. By this, I mean that they have all the genetic material to replicate (DNA & RNA). Viruses, in contrast, contain a piece of genetic material that is encapsulated by a protein coat known as a capsid. Because viruses only have a portion of genetic material, they have to infect a host organism and inject its material into the host and use the host to do the work for the virus. Since bacteria can "live" on its own and viruses cannot, bacterial infections can be treated with medications while viral cannot. In comparison of size, viruses are about 100 times smaller than bacteria. About of 90% of known bacteria live in a symbiotic relationship with humans. This means that the presence of bacteria is beneficial to both the bacteria and humans. In comparison, most viruses feed of the host to produce more viruses... therefore having no benefit to the host.
