HERES HOW

1. Use the wooden skewer to ﬁsh the DNA

out of the solution. It is harmless. It

comes from a harmless tomato, after all.

2. Take a closer look, but do not eat it —

remember, there are still residues of

dish soap and denatured alcohol on it.

HERES HOW

Can you ﬁnd differ-

ences in the quan-

tity of DNA in each

of the samples list-

ed to the left? One

of the experiments

should yield no ge-

netic material at

all. Why not?

Retrieving the

genetic material

YOU WILL NEED

→ wooden skewer

→ test tube of isolated DNA

from Experiment 

Tomato DNA

in a test tube

Every time you eat a tomato salad, you are

also eating a small quantity of tomato

DNA. One kilogram of food contains

between . gram and  gram of DNA.
