this lesson students are introduced to the process of
recombinant DNA through the imaginary creation of chocolate
flavored cherries. Students use a paper simulation to
model using restriction enzymes to remove a gene from
one plant and insert it into another.
Students will be able to:-
1. Identify start and stop sequences in DNA.
2. Model using restriction enzyme and ligase to remove sections of DNA and

Content Area C – The
Molecular Basis of Heredity
- In all organisms, the instructions for specifying the
characteristics of the organism are carried in DNA, a larger
polymer formed from subunits of four kinds (A, G, C, and
T). The chemical and structural properties of DNA explain
how the genetic information that underlies heredity is both
encoded in genes (as a string of letters) and as replicated
(by a templating mechanism). Each DNA molecule in a cell
forms a single gene.
Content Area C – The Interdependence of Organisms
- Human beings live within the world’s ecosystem. Increasingly, humans
modify ecosystems as a result of population growth, technology, and consumption.
DNA, scientists use restriction enzymes to cut DNA into its
parts. New genes can be added to sections or specific genes
can be removed altogether.
