What do bacteriophage's do in genetic engineering?

Answer 1

To duplicate, viruses insert their genetic material into a host cell along with enzymes. The host cell's internal replication machinery is hijacked, and the cell begins producing the proteins to make new viruses.

In genetic engineering, the viral DNA is changed (through a variety of techniques) to include the altered genetic material that is intended to change or replace pieces of the host's genome. It also usually includes a "repair protein" that keeps it from killing the host cell.

Special receptors on the surface of the virus allow it to attach to the appropriate cells (for instance certain adeno-associated viruses can insert information specifically into chromosome 19), and the modified DNA is introduced via the usual method of viral reproduction. Instead of replicating new copies of the virus, the cells begin to copy the new genetic material, which then is incorporated into the host's genome.

Answer 2

They are the vectors by which the genetically engineered material is injected into cells. A part, or all of the bacteriophage's genetic material is excised and the material of interest in put into the capsid of the phage. Then the phage does what phages do; " infect bacteria. Thus the engineered material is delivered to the cells of interest in this process.

Answer 3

Doctors and bio scientists who work with viruses and bacteria take there DNA and figure out how to stop the bacteria and viruses
