Question

Who proved transforming principle?

• A. Griffith.
• B. Avery.
• C. Watson.
• D. Franklin.

Hint:

Griffith's experiment provided the first evidence of genetic transformation, but it was later research by Avery, MacLeod, and McCarty that identified DNA as the transforming principle.

Answer 1

The Correct Option is A

The transforming principle was first demonstrated by Frederick Griffith in 1928. Griffith's experiment showed that a non-virulent strain of bacteria could be transformed into a virulent strain when exposed to heat-killed virulent bacteria, indicating that some "transforming factor" was responsible for the genetic transformation. This discovery laid the groundwork for later work by Avery and others, who identified DNA as the transforming principle.
