Meselson-Stahl
experiment
The individual
strands of these duplexes all are entirely heavy
or entirely light. This pattern was confirmed
experimentally in the mesolson-stahl experiment
of 1958, which fallowed the semi conservative
replication of DNA through three generations of
growth of e.coli. when DNA was extracted from
bacteria and its density measured by
centrifugation, the DNA formed bands
corresponding to its density-heavy for parental,
hybrid for the first generation, and half hybrid
and half light in the second generation.
