<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>

Explanation:
The half life is the time taken for a half of a radioactive material or substance to decay to half.
After the passing of the half-life, only half of the original material will remain. Now, let us follow the half-life sequence of this decay;
One half-life
Original: 1000cm
one half life = 500cm
Two half-lifes
Original: 500:
half-life = 250cm
Three half-lifes
Original : 250cm
Half life = 125cm
Four half-lifes
Original: 125cm
Half life = 62.5cm
Five half-lifes
Original: 62.5cm
Half-life = 31.25cm
Six half-lifes
Original: 31.25cm
Half-life = 15.625
