How do bacteria use transformation?

Answer 1

Transformation is the uptake of naked DNA fragments from the surrounding environment and the expression of that genetic information in the recipient cell, meaning the recipient cell has now acquired a characteristic that it did not previously have. Transformation was first identified by Fredrick Griffith in Streptococcus pneumonia.

For example, if the recipient cell has taken a segment of foreign DNA that codes for antibiotic resistance, the recipient cell will naturally exhibit antibiotic resistance trait as well.
