16 What is the major scientific achievement of Fredrick Griffith in 1928?
Defined DNA as a transforming factor Declared that chromosomes control heredity Stated that dead bacteria can somehow change living bacteria Used radioactive tagged bacteriophages to support the idea that DNA is the hereditary material Declared that DNA is replicated semi-conservatively 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28
