Question

Which of the following scientists are not correctly matched with their respective discoveries?

• A. G. Mendel - Proposed that “factors” were being passed down, unchanged, from the parents to the offspring through gametes, over successive generations.
• B. W. Sutton - Gave the chromosomal theory of inheritance by uniting the knowledge of chromosomal segregation with Mendelian principles.
• C. Griffith- Performed experiments to determine the biochemical nature of enzymes such proteases, RNases, etc.
• D. T.H. Morgan - Coined the term linkage, performed several dihybrid crosses in Drosophila.

Answer 1

The correct option is C Griffith- Performed experiments to determine the biochemical nature of enzymes such proteases, RNases, etc.

G. Mendel proposed that “factors” were being passed down, unchanged, from the parents to the offspring through gametes, over successive generations. He is regarded as ‘the father of genetics’.

W. Sutton, along with Boveri, united the knowledge of chromosomal segregation with Mendelian principles and gave the “chromosomal theory of inheritance”. They observed that the behaviour of chromosomes was parallel to the behaviour of Mendelian factors(genes).
T. H. Morgan carried out several dihybrid crosses in Drosophila, studied sex-linked genes along with their inheritance patterns, found their physical association on chromosomes and coined the term “linkage” for this behaviour. The term ‘recombination’ was also coined by Morgan.

Griffith's transforming principle experiment was performed in 1928 wherein he showed that living R-strain bacteria were somehow transformed by the heat killed S-type bacteria to become virulent (disease-causing).
