In the 1920s, Frederick Griffith conducted an experiment in which he mixed the dead cells of a bacterial strain that can cause pneumonia with live cells of a bacterial strain that cannot. When he cultured the live cells, some of the daughter colonies proved able to cause pneumonia.

Which process of bacterial DNA transfer does this experiment demonstrate?

Answer :

Final answer:

Frederick Griffith's experiment in the 1920s demonstrated the process of bacterial transformation, where genetic material is transferred from one bacterium to another.


Explanation:

In the 1920s, Frederick Griffith conducted an experiment in which he mixed the dead cells of a bacterial strain that can cause pneumonia with live cells of a bacterial strain that cannot. When he cultured the live cells, some of the daughter colonies proved able to cause pneumonia. This experiment demonstrates the process of bacterial transformation, which is the transfer of genetic material from one bacterium to another through the uptake and incorporation of extracellular DNA.
