Question

Griffith's transformation experiments

Select one:
a. were designed to show the effect of heat on bacteria.
b. resulted in DNA molecules becoming proteins.
c. caused harmless bacteria to become deadly.
d. changed proteins into DNA.

Answer 1

Griffith's transformation experiments involved the transfer of genetic material from one bacterium to another, resulting in a change in the characteristics of the recipient bacteria. It provided initial evidence of the transfer of genetic material through transformation.

Step-by-step explanation:

Griffith's transformation experiments involved the transfer of genetic material from one bacterium to another, resulting in a change in the characteristics of the recipient bacteria. He demonstrated this by exposing live, nonpathogenic bacteria to heat-killed pathogenic bacteria, which caused the nonpathogenic bacteria to become pathogenic. This process is known as transformation, and Griffith's experiments provided initial evidence that genetic material could be transferred between bacteria. It was later determined that the transforming principle responsible for this transfer was DNA.
