The process by which Pneumococcus transfers DNA between living type RII and heat-killed type SIII cells is known as __________.
A)transformation
B)replication
C)transduction
D)ligation
E)conjugation

Question

Quizplus · Accepted Answer

The process described involves the transfer of DNA from one bacterial strain (heat-killed type SIII) to another (living type RII) through direct uptake of genetic material, which is characteristic of transformation. Replication refers to the copying of existing DNA molecules, transduction involves DNA transfer through viruses, ligation involves joining two DNA fragments together, and conjugation involves transfer of DNA through physical contact between cells.
