Comparative Story


A car manufacturing company had a
dilemma…


They had a high powered engine in
a car & were certain it would be a
high speed machine!


Unfortunately the body of the car
was far too heavy, and it just
slugged along …


Comparative Story Cntd.


Suddenly they had a brainwave …


They decided to take the high
powered engine & insert it into the
shell of another car with a lighter
frame from a different factory.


This resulted in their much dreamed
of high speed machine!!

Consider This


Take the old car…


Imagine the car as the
cell of
interest


Imagine the engine as the
gene of
interest

Cell of
interest

Gene of
interest

Consider This


Take the lighter car…


Imagine the factory as the
bacterium cell.


Imagine the light framed car as the
plasmid.


The
plasmid
was taken out of the
bacterium cell.

Bacterium
cell

plasmid

Consider This


The
gene of interest

(engine) was
extracted from the
cell of interest

( heavy
car)


The
gene

was then placed into the
plasmid
(lighter framed car).

Gene of
interest

plasmid

Consider This


When the
gene of interest

(high powered
engine) is placed in the
plasmid

(light
framed car) the mechanics for a high speed
machine were available.


This faster car was returned to the
bacterial cell
(factory).

Consider This


They replicated this model and sold
it all over the world!
