Would genetic engineering be possible if we did not know a great deal about the genetics of bacteria? Explain.
An example of bioremediation is
A) the use of prokaryotes to treat sewage or clean up oil spills.
B) the production of antibiotics by cultured prokaryotes.
C) the application of bacteria to produce transgenic plants.
why do the bacteria grow up to the edge of the area with antibiotics, pause, then continue to grow across the area with antibiotics?
A) The antibiotics caused mutations in the DNA of the bacteria, making them resistant to the antibiotics.
B) The bacteria mutated as a survival response to the presence of antibiotics, enabling the bacteria to become resistant to the antibiotics.
C)A few bacteria experienced random mutations in their DNA, which allowed some of them to grow even though antibiotics were present.
D) Researchers added antibiotic resistant bacteria to the culture, so that the bacteria would continue to grow across the area with antibiotics.
