Your grammar for this question is not very good however, I believe I can answer your question.
If they do get change so they can only survive in a certain condition in a laboratory, I would most likely be to make the bacteria not able to survive Outside the lab. In other words, they don't want it getting out. This would be because they usually give the bacteria a resistance to certain antibacterial solutions so that when they cultivate he bacteria, the bacteria that did not accept the plasmid will die from the antibiotic that got mixed into the Agar. In other words, the only bacteria that would grow are the bacteria have accepted the plasmid.
B. They divide quickly -apex
Recombinant plasmids of bacteria
two conditions bacteria need to live
What can protect bacteria from harsh conditions for even millions of years?
They can reproduce very quickly
A recombinant sequence of DNA is a sequence of DNA that comes from more than one source. Examples of recombinant DNA are plasmids that are put into bacteria. The plasmid comes from the bacteria (or a bacteria at least) but a target gene has been added (say the lac operon gene that allows bacteria to thrive on lactose), this plasmid is now a recombinant DNA sequence.
A recombinant protein is a protein that is derived from recombinant DNA.Using recombinant DNA and inserting it to a plasmid of rapidly reproducing bacteria enables the manufacture of recombinant protein. These recombinant proteins can be variety of types, the can be Antibodies, antigens, hormones and enzymes.
Bacteria reproduce very quickly.
Bacteria reproduce very quickly.
Because growing bacteria in a laboratory is done under strict conditions, producing pure strains free from contaminants.

Genetic engineering involves the use of recombinant DNA technology, the process by which a DNA sequence is manipulated in vitro, thus creating recombinant DNA molecules that have new combinations of genetic material
