<span>It was the culmination of research in the 1930s and early 1940s at the Rockefeller Institute for Medical Research to purify and characterize the "transforming principle" responsible for the transformation phenomenon first described in Griffith's experiment of 1928: killed Streptococcus pneumoniae of the virulent strain type III-S, when injected along with living but non-virulent type II-R pneumococci, resulted in a deadly infection of type III-S pneumococci.</span>
Answer:
Option B , Binding Energy
Explanation:
The energy in combining two nucleus is lost in binding them. This binding energy is too large that it causes significant loss of mass and is calculated using the Einstein’s theory of relativity.
When two nucleons combine , mass defect is caused which leads to loss of mass associated with energy and therefore the mass of nucleus is less than the mass of nucleons.
Hence, Option B is correct.
The answer would be B. nucleic acids.
The place where these molecules fit is called the active site .
