Solution
The correct option is C Avery, MacLeod and McCarty
- Prior to work Avery, MacLeod and McCarty, genetic material was thought to be protein. Avery and his colleagues showed that DNA was the key component of Griffith's experiment, in which mice are injected with dead bacteria of one strain and live bacteria of another, and develop an infection of the dead strain's type.
- Sutton along with Boveri proposes the chromosal theory of inheritance.
- Watson and Crick proposed the double helical structure of DNA.
- Benzer proposed model of gene and how they affect behaviour of an organism.
- So, the correct option is 'Avery, MacLeod and McCarty'.
