Re: Definition of Undergraduate Research



Hi,
I thought you might enjoy a note I received from a lady who lives in a
country town in England, relating a trip to the "Big Smoke" (an outdated
term for London), with her husband and nine year old, concerning a visit to
the Wellcome Museum.

and extracted DNA from an onion, BRILL!

How???

I thought you would know how... ;-)


You take an onion
chop it up faily small
put a few drops of detergent in a large test tube and
then add abut 50ml of water.

put onion and detergent mixture in another bowl and liquidize.

Filter this mixture back into the test tube so there is about 30mls of
the liquid.

GENTLY add to this liquid two drops of something, can't remember what we
used but you could use pineapple juice as it is chemically more or less
the same as this stuff.

Put lid on tube and invert gently and revert


VERY GENTLY pour alcohol into the tube so that it floats on the other
solution.

Then the strands of DNA from the onion become apparent between the layers
of liquid, this is harvested with an appropriate implement and stored...



There you are , easy when you know how!

Love

Janine
