The conservative method is incorrect because during the
first generation of the E. Coli DNA growth, modified to be
almost entirely composed of Nitrogen-15 containing
nucleotides, the data resulted in 100% of the DNA being

The DNA replication experiment is important because
although it was done in 1958 it has modern qualities.
Meselson and Stahl represented a new way of doing

In the semiconservative hypothesis, proposed
by Watson and Crick, the two strands of a DNA molecule
separate during replication. Each strand then acts as a
template for synthesis of a new strand.
The conservative hypothesis proposed that the entire DNA
