Frederick griffith performed an experiment in which a live culture of avirulent "rough" strain streptococcus pneumoniae bacteria were mixed with dead cells of virulent "smooth" streptococcus pneumoniae bacteria. subsequently, the "rough" bacteria were "transformed" into "smooth" bacteria capable of killing mice. this experiment demonstrated that

Transformation is the ability of bacteria to absorb the DNA of other types of bacteria from the external environment into the body and incorporate it in its own DNA.
Then this the DNA from outside is translated, making proteins of other bacteria.
In this experiment, DNA of dead virulent smooth bacteria was taken up by rough bacteria.
Rough bacteria start making proteins of smooth bacteria and become virulent smooth bacteria.

The study of genes is called genetics. There are two types of the gene, one of them is recessive and the other is dominant.

This experiment demonstrated that bacteria have the ability to transform.

What is transformation?

Griffith concluded that the R-strain bacteria must have taken up what he called a "transforming principle" from the heat-killed S bacteria, which allowed them to
"transform" into smooth-coated bacteria and become virulent.

Transformation is the ability of bacteria to absorb the DNA of other types of bacteria from the external environment into the body and incorporate it into its own DNA.

Then the DNA from outside is translated, making proteins of other bacteria. In this experiment, the DNA of dead virulent smooth bacteria was taken up by rough bacteria.

Rough bacteria start making proteins of smooth bacteria and become virulent smooth bacteria.

Hence, the correct answer is mentioned above.
