Who supported Griffith experiment by molecular explanation (a) Watson and Crick (b) M. Nirenberg and M. Khorana (c) Miescher and Fleming (d) Avery, Mc Carty and MacLeod
Answers
Griffith's experiment was an experiment done in 1928 by Frederick Griffith.
Avery, McLeod and McCarty and by Hershey and Chase.
In this experiment, bacteria from the III-S strain were killed by heat, and their remains were added to II-R strain bacteria.
While neither harmed the mice on their own, the blend of the two was able to kill mice. Frederick Griffith experiments were conducted with Streptococcus pneumoniae.
Option-D
Explanation:
Griffith experimented on Streptococcus pneumonia and identified that the heat-killed S bacteria (virulent), when injected with live R bacteria (avirulent), killed the mice.
This lead to the conclusion that there is some molecule which has transformed the avirulent R bacteria into the virulent bacteria or S bacteria. He called this substance as the "Transforming principle. "
Later the experiment was followed by the Avery, McLeod and Mc Carty in 1944 and identified that the transforming particle was the DNA.
Thus, Option-D is correct.
