Bacteria have developed a "Halt! Who goes there?" approach to gene exchange to prevent unrestricted incorporation of DNA into the cell. It is called ________ and ________.

Question

Quizplus · Accepted Answer

The "Halt! Who goes there?" approach to gene exchange is referring to the restriction modification system, where bacteria use restriction enzymes to cut foreign DNA and modification enzymes to protect their own DNA from being cut. This prevents unrestricted incorporation of DNA into the cell, as the foreign DNA will be cut and degraded. Conjugation, transformation, transposition, transduction, mobilizable and F plasmids are all mechanisms of gene transfer.
