Question

Transformation in Diplococcus by heat-killed extract was discovered by

• A. Brown
• B. Griffith
• C. Fleming
• D. McLeod

Answer 1

The correct option is B Griffith

Griffith's experiment was an experiment done in 1928 by Frederick Griffith. He performed experiments on two strains of Streptococcus pneumoniae or Diplococcus pneumoniae bacteria, a type III-S (smooth) which was virulent, and a type II-R (rough) strain which was nonvirulent. The experiment showed that bacteria are capable of transferring genetic information through a process known as transformation.

Thus, the correct answer is 'Griffith.'
