In a Davis U-tube experiment, you add a different strain of autotrophic bacteria to each side of
the apparatus. After allowing time for growth, you transferred and grew the bacteria on a plate
with minimal medium and noticed the growth of prototroph's. By which process did this genetic
transfer possibly occur if... There was DNase enzyme (breaks down free-floating DNA) present
in the medium? There was no DNase enzyme in the medium? There was DNase enzyme
present in the medium and the sintered glass filter was removed from the U-tube apparatus (no
separation between bacterial strains)?
Solution
a) Genetic transfer would not have occurred here because there was presence of sintered glass
filter, so even if DNase enzyme would have been present there would not have been any genetic
material transfer.
b) Genetic transfer would not have occurred here because there was presence of sintered glass
filter, so even if DNase enzyme would not have been present wouldn't have cause the genetic
material transfer.
c) Since there was no seperation between bacterial strain, chances of genetic transfer between the
strains are high. Also presence of DNase enzyme to break down DNA helps in further integration
of new DNA into bacterial strains.
