Which of the following are methods by which bacteria can be induced to take up recombinant DNA molecules?
A) Heat shock.
B) DNA "guns" which spray the DNA at very high speeds.
C) Electroporation
D) Phage or virus infection.
E) All of these are used to transform bacteria.

Question

Quizplus · Accepted Answer

All of these methods are used to introduce recombinant DNA into bacteria. Heat shock and electroporation temporarily create pores in the bacterial cell membrane to allow DNA entry. DNA "guns" physically propel DNA into cells, and phage or virus infection is a biological method where viruses are engineered to carry and deliver recombinant DNA into bacteria.
